Highest quality rubber sealing components

PTFE is a kind of synthetic polymer material. The main base of PTFE is carbon atom. And the fluorine atom is evenly distributed around the carbon atom and forms the compact protective screen. Therefore, PTFE has the very excellent physical mechanical property. It can not only resist the strong acid, strong alkali and strong oxidant but also can bear high temperature. To some degree, its property surpasses the property of glass, ceramic, stainless steel and gold. Its working temperature ranges from-100 to 100 Celsius degrees.

As a kind of sealing material, PTFE is applied by different ways. The good corrosion resistance, stable physical property and temperature endurance make contribute to its excellent sealing ability. As a result, it is very applicable in the following industries, such as oil, chemical, electric and steel. The applicable media are also in a wide range, including water, oil, acid liquid and other chemical liquid. PTFE seals are typical applications for the PTFE material. As its name implies, PTFE seals are made through cutting the PTFE rod, pipe or plate. The main material is PTFE and so this gasket naturally inherits all features of PTFE. It includes flat gasket, V-gasket, piston ring and ball valve gasket.

In terms of machinery, you really cannot take chances with performance, as a lack of it will certainly reflect badly on manufacturing methods.

Seals that are fabricated with tight tolerance

Hollow orings are used as sealing elements, as energizing elements for hydraulic slipper seals and wipers and thus cover a large number of fields of application. Hollow orings offer a low closure force alternative to solid orings. As required for many lids and doors, hollow orings are used in applications that require the seal to stay in the groove while not overfilling the gland or warping the enclosure lid or door. Hollow orings consist of an elastomer inner ring and a seamless sheath which surrounds the elastomer ring. Similar to PTFE orings hollow orings are used wherever the chemical resistance of normal elastomer orings are not sufficient. The required elasticity is provided by the elastomer ring, the chemical resistance by the seamless sheath.

Hollow orings are chemical resistant, a wide range of thermal stability, low permeability and low friction. Hollow orings are especially useful for these applications. Enclosures that use flat-panel sealing are not typically fabricated with tight tolerances and are often made from thin metal or plastic. And large enclosures are more susceptible to leakage due to tolerance-gap runout along the sealing perimeter. Low closure force may also be desirable to decrease the loading on hinges and fasteners.

Encapsulated hollow seals consist of an elastomer inner ring and a seamless sheath which surrounds the elastomer ring. Similar to PTFE Orings encapsulated and hollow seals are used wherever the chemical resistance of normal elastomer Orings are not sufficient.

Deflected wide range of seal geometries

A lip seal is a rotary seal incorporating a deflected lip seal geometry. Anti-rotational devices such as flanges and O-rings are often utilized to prevent the seal from rotating with the shaft. Standard and custom sizes are available with a wide selection of PTFE materials. Lip seals are suitable for sealing corrosive and abrasive media. A wide range of geometries and materials are available, depending on specific application requirements. Lip seals are often used on motors and compressors and other components with high speed rotary shafts due to their ability to resist wear even while pressurized.

The most common lip shape is the chamfered or back-beveled design and is available with the V and C Series spring types. This design allows for ease of installation and permits lubrication to nest under the lip and feed through in reciprocating dynamic applications. The result is a microscopic film of lubrication that increases seal and hardware service life. Since the footprint (contact point) of a chamfered lip is a single point, all of the sealing force is concentrated on that point, yielding the highest sustainability and lowest friction.

Applications often involve medias with abrasive particles that can get caught between the seal lip and the mating hardware. This increases wear to both the seal and the mating surface. To prevent particles from accumulating, the scraper lip design is available with all three spring types. The scraper lip contact point is positioned directly over the load point of the spring in each design for maximum scraping action. The scraper lip can be positioned on the ID, OD or both. The scraper lip also stays in place better in a stepped gland where the step is not very large.

The beaded shape contacts the surface in much the same way as an O-ring, and is available with the V and H Series spring types. Similar to the chamfered lip, it is easy to install and helps to lubricate the reciprocating sealing surface. In fact, the beaded lip yields a film of oil that is slightly thicker than that of a chamfered lip, making it advantageous for applications with rapid reciprocating motion. Darcoid Nor-Cal Seal is an excellent supplier of lip seals.

Oring to its unique features, it is widely used in a lot of industries, such as machine tool, boat, automobile, metallurgical machinery, chemical machinery, engineering machinery, building machinery, plastics, agriculture and different instruments.

Orientations and different types in hydraulic seals

            

                    There are plenty of tools and equipments that are required to carry out industrial and manufacturing processes. The hydraulic seals are one such useful tool that can be used for a number of different purposes. There are, in fact, different hydraulic actions, and each of these actions requires the usage of specially designed tools. These seals are designed to assist in transferring power from a hydraulic system to the linear motion by containing the oil for the pressure. If the oil is not controlled, the pressure within the system will pass, and this in turn, will result in the failure of the entire system. In addition to that, these seals can also keep away the dirt from the system, by means of which the entire hydraulic action remains efficient.

Hydraulic seals are products that include types such as rod seals, flange packing and U-cups. They are specifically designed for applications that require high pressure such as those of hydraulic cylinders. It is said to have a wide array of orientations and different types. Before going further into the orientation and types of hydraulic seals, here are some things to consider when purchasing such industrial products. The diameters of the outer shaft, inner seal and housing bore should be specified. Thickness and radial cross section should also be included in the list of considerations. Service limits such as operating speed and pressure, vacuum rating and temperature should be dealt with accordingly. There are various sealing directions for hydraulic seals.

The first on the list is called a rod seal. A rod seal is a type of radial seal that is fit specifically into the housing bore. The sealing lip is found in contact with the shaft. The second type is known as the Piston seal. This is yet another type of radial seal and is a variation of the rod seal. Instead of the sealing lip found in contact with the shaft, the lip goes in contact with the housing bore. It is in the shaft where the seal is pressed accordingly. The other types of sealing orientations are symmetric and axial seals. A symmetric seal, as the concept implies, work symmetrical or equal to the rod and piston seals. The axial seal on the other hand, goes in contact or in axis with the housing component.

There are two categories for these industrial products. These are dynamic and exclusion seals. A dynamic seal is one that is used in order to separate a fluid from possible contaminants. It is utilized in order to put a gap between moving and non-moving surfaces like those found in piston ring applications. When considering dynamic seals, it is important to focus into a variety of dimensions like inside diameters, outside diameters, axial cross section, radial cross section and housing bore.


Exclusion seals are those that are used in order to separate contaminants from machine bearings. They remove any debris from moving shafts. These hydraulic seals can be sub-classified further into V-ring, scrapers and wipers. V-rings are those made out of rubber while wipers are those with lip seals that are flexible. Scrapers are those that contain scraping edges used in the process of removing contaminants from the bearings. Darcoid Nor-Cal Seals is an endeavor that is into manufacture of sealing and other accessories for machinery.

Seals have been used since ancient times and have evolved into a wide variety of shapes and materials. For those who are not familiar with sealing technology, the number of options available can be confusing. Selecting the most suitable product for a given application can be difficult. This engineering section will assist in product selection by explaining the fundamentals of seal design and material technology.

Darcoid Nor-Cal Seal is a leading distributor of fluid power seals. Darcoid Nor-Cal Seal has been providing standard and custom-made fluid power seals for a wide range of applications and industries for a long time as an industrial global leader and has been providing fluid power seals for various applications including Aerospace and Military markets where quality is of utmost importance. A fluid power seal is a two piece design consisted of standard sized rubber square ring energizing a PTFE cap.

Fluid power seals are widely used in heavy duty hydraulic actuators. Darcoid Nor-Cal Seals deliver top quality fluid power seals that are of excellent quality, stability, long lasting, low friction and give protection from extrusion.

Darcoid is a global leader for diversified products of motion and control technologies and systems. The company provides precision engineered solutions for a wide range of commercial, mobile, industrial and aerospace markets.

When choosing a sealing system, the desired result is ultimately leakage control. Seal design and material improvements have made it possible not only to have seal combinations that provide zero leakage, but also provide extended life in a variety of applications. Aside from the seals themselves, a thorough understanding of system parameters is necessary to obtain the best results. Optimal sealing is best achieved by taking a system's approach to the seal package rather than considering components individually.

Fluid power seals from Darcoid Nor-Cal Seals have been designed specifically to compliment one another to create high performance systems. For instance, pairing a Darcoid's rod seal with a wiper minimizes fluid leakage and maximizes contamination exclusion. The seal element plays a vital role in the hydraulic system. It can prevent the fluid leakage and also can stop the outside air or dust entering into the system. The hydraulic seal elements are the core of the hydraulic equipment. For a hydraulic device to perform better, a good hydraulic seal is necessary, which is the guarantee of the excellent hydraulic device.

Therefore, this device has been widely applied in a lot of sectors, such as industry, agriculture and nation defense. In order to ensure the good performance of the hydraulic transmission device, the hydraulic seal must be compatible with the features of the device. The leakage rate of the hydraulic seal must be very small. With the increase of the hydraulic liquid's pressure, the seal intensity can be improved automatically.

Even though the seal is used in the harsh environment, the leakage rate can not be increased obviously. The seal is often soaked in the fluid and so it easily becomes hard. In order to ensure the long-term sustainability of the seal, the hydraulic seal should be compatible with the liquid. The hydraulic seal must be characterized by features, such as heat, pressure and abrasion resistance and also good elasticity. Technological innovations and valued added services allow us to engineer your success with leading edge material development, experienced design and application engineering, quality and outstanding customer service.

Distinct advantage over homogeneous diaphragms

Fabric reinforced diaphragms utilize a layer of an engineered fabric material as part of the diaphragm construction. This layer of fabric give tremendous design flexibility. A very thin-walled diaphragm can withstand high pressures while remaining very flexible and responsive to minor pressure variations. A fabric reinforced diaphragm limits the stroke and provides a frictionless seal. These diaphragms generally cost less, have more tolerance range, and do not require hardened super finishes or lubrication. The function of a diaphragm is the most important factor in its design and manufacture. Simple diaphragms move from one position to another, such as pressure switches and solenoid valves. Diaphragms can be used as shock absorbers as in a dash pot or as dampening devices in pulsating systems. Diaphragms can also be used as barriers between fluids and gases, such as in a pressure drop on the fluid side.


Fabrid reinforced diaphragms are used in pumps, such as automobile fuel pumps, hand pumps, and diaphragm air compressors. In these cases an outside mechanical force is actuating the diaphragm. This functions to displace a volume of media. In the case of a pump the diaphragm creates a low pressure area causing the fluid or gas to move into this area. In all the above cases the function of the diaphragm will generally be the determining factor when considering the type of construction, the material composition, fabric design (weave/knit), and the type of polymer.


Supported diaphragms are produced from a wide variety of fabric, varying strength, weights, and weaves. The fabrics themselves range from natural fibers, such as silk and cotton to the man-made fibers and high strength arimids. The elastomeric coatings can be put on both sides of the fabric in equal thickness or an unbalanced coating. Many applications require elastomeric coatings on only one side such as applications where the pressure differential is in one direction. When knit fabrics are employed, the coating is usually on one side and the same side as the pressure. This allows the fabric to support the coating on both sides for flat diaphragms.


The selection of the fabric substrate, in terms of strength, weight and flex life will greatly depend on the application. Fabric reinforced diaphragms have a distinct advantage over homogeneous diaphragms. Supported diaphragms have less tendency to stretch under pressure conditions. Most importantly, fabric substrate takes all of the stress from the rubber leaving the rubber to work in the least stress conditions.


Darcoid Nor-Cal Seal offers a wide range of elastomer compounds including NBR, EPDM, neoprene, epichlorohydrin, silicone, fluorosilicone and fluorocarbon, as well as polyester, nylon, high temperature nylon and silk fabric reinforcements. Fabric reinforced diaphragm seals are an ideal solution where accurate, consistent response is required for changes in hydraulic or pneumatic pressures, maintaining zero leakage, and offering almost zero friction without the need for lubrication. Darcoid Nor-Cal Seal supplies fabric reinforced diaphragms for usage in applications in many industries including automotive, aerospace, semiconductor, medical, instrumentation and process control industries, they offer an inexpensive solution to design problems.

Basically an O-ring is used to block a pathway that fluid or air may escape through. O-rings are usually put into a groove to hold them in place and then squeezed between two surfaces. When an O-ring is squeezed between two surfaces it shall be taking up the clearance and blocking the pathway that the fluid or air wants to escape through. After an O-ring is applied by squeezing, the rubber once again takes up its original shape. This is how the O-rings seal under low to no pressure. When pressure is applied to the system this also helps the O-ring seal by pushing the O-ring against the groove wall opposite the direction of the pressure and forcing it expand perpendicular to the direction it is being squeezed by the pressure.

Darcoid Nor-Cal Seal is an authorized distributor for Parker seals, O-rings and the likes. These seals have a wide selection of compounds that can meet your application requirements.

Since O-rings can not be made exactly to their dimensions every time, manufactures are allowed to make them within range of their original dimensions. Variations in the rubber compound and in the manufacturing process cause slight variations in the shrink of the material and effect the finished size of the O-rings. O-rings are commonly made of rubber but they can also be made with plastic or metal. Several different type of rubber compounds exist on the market today because of the different temperatures, chemical exposures and environments that O-rings are subjected too. O-rings come in many sizes, hardness, elastomer and colors to suit various applications.

Prime objectives of Emi shielding seals

The effect of the growth experienced in the electronic industry and the adverse use of electronic equipment in computations, communications, biomedical automation, space and many other reasons has resulted in electromagnetic interference. Commonly referred to by its initials EMI, this problem is bound to be severe in the near future, unless a method of control is arrived at.

The suppression of EMI should be a prime objective for anyone who is involved in this trade, and hence EMI shielding. This can be termed as the reduction of the electromagnetic field, in any given space by using barriers to block the field. These barriers are made of magnetic materials. There are various ways to apply shielding. Shielding is in this case applied to enclosures, isolating all electrical devices, and to cables to keep the wires safely from the surrounding where they run.

In a world that is becoming more and more dependent on electricity, and all its devices, there is need for protection of all the electrical equipment used in all places, both at home and work. EMI shielding sealing solutions are being used in countless devices in the office, home, factories as well as laboratories.

Despite the ever presence of EMI, many, engineers physicists, and other people involved in technology are puzzled by the basic elements involved and all the sealing materials that serve to protect electronic equipment.

Electromagnetic radiation is made up of electric and a magnetic field consists of two fields, electric and magnetic. The electric field is responsible for the production of forces, which are on the charge carriers in a conductor. When an electric charge is applied to the surface of a conductor, in brings in a current, which causes charge displacement within the conductor, cancelling the field applied inside, which causes the current to stop.

The common materials that facilitate EMI shielding seals include metal screen, sheet metal, and metal foam. Different positioning techniques are applied when one is shielding. During shielding, using these materials, one should be careful to make sure that any holes found on the mesh or shield are smaller, compares to the wavelength of radiation. This radiation is what is intended to be kept out, and if this is not adhered to, the enclosure or surface shielded will fail to approximate the conducting surface that is unbroken.
