Common phenomenon for rubber o-rings

A fluid power seal is a two piece design comprised of a standard size rubber square ring energizing a rectangular shaped PTFE cap. The fluid power seals from Darcoid Nor-Cal Seals offers excellent stability, long wear, low friction and extrusion protection.

The fluid power seal is commonly used in applications such as agriculture hydraulics, mobile hydraulics, machine tools, and hydraulic presses. Darcoid Nor-Cal Seal is the world’s leading diversified manufacturer of motion and control technologies and systems, providing precision-engineered solutions for a wide variety 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 complement 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. Darcoid's rod seals are designed with knife-trimmed lips to ensure the best possible film breaking.

Teflon Seals, as the name suggest are back ups to prevent extrusion in rubber o-ring sealing systems. It is a common phenomenon for rubber o-rings to extrude especially with present day fluid systems that are a combination of high pressures and high temperatures. And this is a situation where the Teflon backup rings play a significant role in preventing o-ring extrusion.

These Teflon seals are ideal to be used as backup rings in aerospace applications especially in the Aerospace Standard AS-568A Uniform Numbering System. We assure you of the quality of these types of O-rings, as they have been successfully approved by fluid systems designers for its added flexibility in size selection.
These varieties are apt for use in sealing systems that are frequently subjected to severe duty cycles, or where pressures exceed 3,000 psi and temperatures are above 275 degrees Fahrenheit.

Customized O-rings and Parker seals of nearly infinite size range

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.

Diaphragms are also 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 fabric reinforced diaphragms will generally be the determining factor when considering the type of construction, the material composition, fabric design (weave/knit), and the type of polymer.

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.
Parker seals and O-rings are excellent for preventing various kinds of fluids/liquids or gas loss. These Parker seals have the potential to function both as a static as well as a dynamic seal. As a static seal, it is immovable and is used simply for containing pressure or maintaining a vacuum. On the other hand as a dynamic seal it has reciprocating capabilities. The Parker seals are the most preferred options for engineers across the world for all their sealing needs. This is because these are dependable, safe and long-lasting.

Today, these are used in industry sectors ranging from automotive to fluid power to semiconductor processing. You can find Parker seals in passenger cars, construction equipment, heavy duty trucks, refrigeration and air conditioning components, commercial and military aircraft, pharmaceuticals, oil and natural gas rigs, kitchen and bath fixtures, surgical instruments, fuel handling equipment and drug delivery devices.

Thermal and chemical resistance of Orings

Oring to its high strength, durability, low maintenance, ease of availability, good conducting properties, metal is used widely in almost every industrial sector. Metal is used in many forms like pipes, sections, wires, rods, sheets, etc. In many of the industries metal pipes or hollow sections are used to convey fluids (gases or liquids) from one place to another.

Just as the function of a sealant is to prevent leakage or to seal any openings there are materials whose purpose is to isolate thermal environments from each other on its two sides. Hot and cold Insulation materials are used to provide a layer of insulation which reduces or minimizes the heat flow. Besides good thermal resistance good hot and cold insulation materials have properties like being inert to a wide range of chemicals (high chemical resistance), physically stable or tough, etc. Depending on the need, a suitable hot and cold insulation material is used to provide thermal barrier.

Hollow seals 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 O-Rings hollow O-Rings are used wherever the chemical resistance of normal elastomer O-Rings are not sufficient. The required elasticity is provided by the elastomer ring, the chemical resistance by the seamless sheath.

Advantages of hollow seals are that they are chemical resistant, a wide range of thermal stability, low permeability and low friction. Hollow seals are used as sealing elements, as energizing elements for hydraulic slipper seals and wipers and thus cover a large number of fields of application. Encapsulated hollow seals consist of an elastomer inner ring and a seamless sheath which surrounds the elastomer ring. Similar to PTFE O-Rings encapsulated and hollow seals are used wherever the chemical resistance of normal elastomer O Rings are not sufficient. The required elasticity is provided by the elastomer ring, the chemical resistance by the seamless sheath.

There are no fields of industry where hollow seals are not used. From an individual seal for repairs or maintenance to a quality assured application in aerospace, automotive or general engineering.

Excellent Orings to suit the needs of its customers all across

Sealing requirements can be fulfilled with spectrum of options. The options vary as per specific usage. If you are facing problems with your sealing system, try O-rings sealing solutions and get the best of seals available. As different industries look for diverse variation, there are options to fulfill their demand. O-rings are the finest type available. These O-rings are known for their quality and superior sealing abilities.

O-rings are round shaped rings made out of elastomeric compounds that consists of natural or synthetic rubber. With innovative designing and impeccable engineering, Darcoid offers these excellent O-rings to suit the needs of its customers all across. This is because these are dependable, safe and long-lasting.

These O-rings are being widely in use in industrial sectors ranging from automotive to fluid power to semiconductor processing. O rings are generally being used in cars, construction equipment, heavy duty trucks, refrigeration and air conditioning components, commercial and military aircraft, pharmaceuticals, oil and natural gas rigs, kitchen and bath fixtures, surgical instruments, fuel handling equipment and drug delivery devices and many more applications.

Metal O-rings are the metallic variants of commonly used elastomeric O-rings. They are typically used in static sealing applications that are incompatible with the physical and chemical characteristics of elastomeric O-rings. These O-rings have high tolerance to radiation as well as high vacuum, and are generally used for flanged applications. Ideally, metal O-rings are placed in both open and closed grooves and axial pressure is applied between two parallel surfaces. Furthermore, grooves that hold the O-rings are designed to be perpendicular to the direction of the fluid flow. When placed between surfaces and compressed to a predetermined height, deforms and creates contact between the jointing and sealing faces. Inherently, O-rings' metallic elasticity displays a reasonable deflection and creates maximum sealing contacts during operation to ensure the sealing action. In addition to elastic deflection of the metal, structural builds of the O-rings also play an important role in creating the sealing force. Although most metals can be used for manufacturing metal O-rings, the choice of metals should be such that the linear expansion co-efficient of the O-ring metal varies slightly from the linear expansion co-efficient of the metal of jointing surfaces. Metal O-rings are vulnerable to rusting unlike elastomeric O-rings, and as such, are coated with a suitable material to avoid rusting. This material is softer than the base metal and serves an additional purpose of negating the effect of surface abnormalities. The coating materials that are typically used are soft metals, such as silver, and non-metals like PTFE.

Whether it's the flow of liquid or air, O-rings are exceptionally effective in making the seal highly efficient. The quality of the seal plays a pivotal role and the manufacturers must take extra care while choosing the raw materials and production techniques. With high tech solutions and advanced methods, the kind of sealing devices from Darcoid Nor-Cal Seal are immensely satisfactory and offer desired results every time the product is used for varied industrial usage.

All industries right from mechanical, automotive, pharmaceuticals, and many more choose O-rings for their usability. With years of experience and first rated facilities provided by Darcoid Nor-Cal Seals, their O-rings have witnessed tremendous rise in their popularity. The O-rings are the most preferred options for engineers across the world for all their sealing needs.

High purity PTFE seals

High purity plastic valves and PTFE seals are made from PTFE, PVDF and other high purity plastics. These types of valves are produced by specialty plastic fabricator manufacturers for use in severe and critical service applications for the Pharmaceutical, Defense, Alternate Energy, Semiconductor, Medical and Chemical industries, to remotely control fluid flow. Since these products, including PTFE seals, are most often utilized in a corrosive laboratory environment or clean room automation environment, the high purity plastics of construction ensure the best results against corrosion and their chemical resistances offers long life within the application. Custom fluid control products made from polytetrafluoroethylene (PTFE) and other industrial plastics can be found in a wide variety of specifications to meet the many possible applications and can often be tailor-made to a customer's particular requirements.

PTFE seals are used to remotely control fluid flow. Their use is becoming increasingly popular in a wide variety of industrial applications thanks to their relative simplistic nature and affordable installation cost. With an enormous range of high purity plastic valves on the market, factories and plants throughout the industrial sector are easily able to find the right valve that meets the exact specifications of their intended use.

PTFE seals and valves are electrically actuated to either their open or closed position. The valve components work by allowing or restricting liquid flow depending on whether or not they are subject to an electrical current. The trigger device is normally an electromagnet coil which activates when fed an electric current, attracting a plunger or other valve stem component to changing the state of the mechanical device, this in turn allows or prevents liquid flow. When the electromagnet is deactivated, the plunger is returned to its original position typically by means of a return spring.
