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.

Pneumatic seals are any of a class of seals used in applications including rotary or reciprocating motions. They are often used in pneumatic cylinders and valves. Pneumatic seals require minimal lubrication when exposed to air in order to create a tight seal. Pneumatic seals may also be exposed to high operating speeds at which the pressure is not high. The difference between pneumatic seals and hydraulic seals is pressure. Pneumatic seals typically have a pressure range of 1 to 150 pound-force per square inch (psi), while hydraulic pressure can reach greater than 10,000 psi.

A typical Hydraulic seal consists of an integral PTFE ring and elastomer ring, providing the properties of an elastomeric ring with a rigid, low friction, Teflon coated (PTFE) working face. Hydraulic seals can have a variety of different cross sections. Hydraulic seals include shaft outer diameter or seal inner diameter, housing bore diameter or seal outer diameter, axial cross section or thickness, and radial cross section.

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.

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. The required elasticity is provided by the elastomer ring, the chemical resistance by the seamless sheath.

Special and high quality seals and gaskets

Die Cutting is a procedure by which a material is cut to an exact design or shape with the help of a die. It is a creative process similar to cookie cutting. It involves the cutting of shapes from plastic sheets using a shaped knife and pressing the edge into one or more layers of sheeting. After completing the cutting, a certain pressure is applied using mechanical or hydraulic presses. Die cutting is sometimes known as dinking or blanking.

Extruded and die cut products like the die cut gaskets are usually supplied as ID/OD tubing type cross-sections and can also be supplied in a variety of different cross-sections such as square, rectangular and triangular.

Uses of parker o rings in multiple industry sectors

O-rings are round shaped rings made out of elastomeric compounds that comprises of natural or synthetic rubber. With innovative designing and impeccable engineering, Parker offers excellent O-rings for its customers across the world. Parker O-rings like all other O-rings are used for sealing. These are excellent for preventing various kinds of fluids/liquids or gas loss. These O-rings has 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 O-rings 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. At present, these are used in industry sectors ranging from automotive to fluid power to semiconductor processing.

Parker o-rings also come in different customized varieties as per their inner diameter: its cross-section diameter: material composition and hardness. And the only factor that is responsible for this is the compression which determines the O-Ring cross section diameter. It is to be mentioned here that the inner diameter of O-Ring should be similar to the inner diameter of the groove: so that it can get stretch and stick to the groove.

There are many uses of parker o rings in multiple industry sectors. They are user friendly and require no smearing or re tightening, once they are installed. Unlike piston seals they require very little room and very light weight. Additionally, they can be recycled and reused if maintained properly and hence they are cost effective sealing solutions even for high performance applications.
