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).

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.
