Home >> O-Rings
The O-ring is the most widely used seal in industry today. It is simple in concept, easy to install, can be used as a double-acting seal, can seal pressures to over 5,000 psi in static and dynamic applications and, best of all, is very economical.While simple in concept, it can be very sophisticated in its applications. O-rings are available in 349 standard inch sizes as set up by the Aerospace Standard 568 published by the society of Automotive Engineers. For O-ring sizes other than these standard AS sizes, specify the actual dimensions desired for the inside diameter (I.D.) and the cross section (W).
The O-ring is a simple and versatile seal that can be used in thousands of applications. O-rings are manufactured in a wide variety of compounds to suit your every need.
Back-up rings are washer-like devices that are used to prevent a seal from extruding through any gaps while under pressure. Back-up rings are not seals themselves, but are usually used in conjunction with O-rings in high-pressure applications. Typical applications include hydraulic cylinders and high-pressure hydraulic systems, and high-pressure valves.
Providing excellent sealing characteristics in a broad range of applications, Quad-Ring® seal’s are available in a full range of standard sizes, in Nitrile and Fluoroelastomer.
For demanding sealing applications when customers require the very best, Kalrez® parts manufactured only by DuPont Performance Elastomers, are the elastomer seals of choice. Supplied in standard O-rings or custom shapes, Kalrez® resists over 1,800 different chemicals while offering the high temperature stability of PTFE (327°C).
Profiles and extrusions custom manufactured to your specifications. Available in inch or metric cross sectional sizes and a wide range of materials.
O-rings consisting of a seamless and uniform PTFE FEP/PFA encapsulation/jacket which completely encloses a core material (either Viton® fluoroelastomer or silicone). The combination of these components creates an o-ring that is virtually chemically inert and compression set resistant for use in harsh sealing environments.
Teflon O-Rings are produced with 100% Virgin PTFE and fabricated to extremely close tolerances and to the highest industry and military specifications.
Metallic O-rings are designed to prevent leakage of gases or liquids under adverse sealing conditions.
O-Rings molded in metal detectable compounds.
O-rings custom manufactured for your specific application needs. Available in inch or metric cross sectional sizes and a wide range of materials
A wide variety of O-rings are standard in our kits, giving you the flexibility and the versatility to find the right fit for your situation.
O-rings prepackaged in poly bags for convenient over the counter sales.
A wide variety of sanitary gaskets and o-rings. Hygienic seals are used widely in the Biotech, Pharmaceutical, Dairy, Food & Beverage, Industrial and Semi Conductor industries to seal clamp connections in sanitary pipe lines. We offer the entire product range of specialty gaskets in several elastomers, and fluoroelastomers.
Vee and Round Urethane drive belts available in FDA/USDA grade materials and a range of durometers and diameters for the specific application. Supplied from cord stock and fabricated to the exact size required, the belts can be bonded on site.
