O-Rings
Compact, reliable seals that absorb the tolerance stack-up between closely mated surfaces in both dynamic and static applications.
An o-ring is a simple and versatile ring-shaped packing or sealing device with a circular cross section (from which the “O” in its name is derived).
O-rings function as compact reliable sealing devices by absorbing the tolerance stack-up between closely mated surfaces in both dynamic and static applications. Although o-rings can be made from a variety of materials, they are commonly molded in one piece from an elastomeric material.
The basic o-ring design has been in use for many years. By the early 1940's, basic size and design information developed for military applications. The decade following WW II saw wider o-ring use in industrial, automotive and medical applications.
Today, billions of o-rings are used for almost every conceivable application. They are used to seal pumps, valves, cylinders, and fittings in passenger cars, trucks, aircraft, farm equipment, industrial hydraulic equipment, home appliances and plumbing. O-rings can also be used in a variety of non-sealing applications, such as bumpers, drive belts, tension bands, conveyors, spacers, and friction drives.
