-211 BLACK CHEMOURS VITON 75D O-RING

The VITON75211 is an AS568-211 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 0.796 in (20.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.074 in (27.28 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to engine and transmission fluids, petroleum oils and fuels, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is known for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in low-molecular-weight organic acids or ketones and esters.

You will find this material specified across high-temperature process equipment, aerospace, and oil and gas.

This item is sold individually under part number VITON75211. Unit weight is approximately 1.373 g. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
