-021 BLACK CHEMOURS VITON 75D O-RING

Part number VITON75021 is an AS568-021 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 0.926 in (23.52 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.066 in (27.08 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists engine and transmission fluids, petroleum oils and fuels, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or amines will shorten service life.

Typical settings include chemical processing, semiconductor equipment, and aerospace.

Stocked as VITON75021 and sold individually. Unit weight is approximately 0.3658 g. Check the compound against your process media, pressure and temperature before committing to a design.
