AS568 rubber o rings

An O-Ring is a simple and versatile ring-shaped packing or sealing device with a circular cross section. The opposite side of an O Ring are squeezed between the walls of the cavity or gland into which the O -Ring is installed. The zero clearance within the gland provides an effective sealing and blocking the flow of liquids, and gases through the glands. Internal pressure dynamics and static. O-rings are available in a variety of materials, in both standard and custom sizes. Our proprietary compounds are designed to perform in a wide range of applications with varying chemical exposures, pressures and temperatures.

Nitrile / NBR: Nitrile (Buna-N) is the most widely used elastomer due to its excellent resistance to petroleum products, operating temperature range (-40°F to +257°F) and one of the best performance-to-cost values. It's an ideal material for aerospace, automotive, propane and natural gas applications. Special Hydrogenated Nitrile (HNBR) compounds can improve resistance to direct ozone, sunlight, and weather exposure while increasing temperature range to +300°F.

O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.

The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.
