This o-ring is supplied in AS568-901 brown Viton® (FKM) 75 Shore A built to an inside diameter of 0.185 in (4.7 mm), a cross section of 0.056 in (1.42 mm), and an outside diameter of 0.297 in (7.54 mm), catalogued under part number VB75901. It creates a positive seal at flange, piston and rod interfaces without added hardware.
Expect good resistance to aggressive chemicals, chlorinated solvents, and many acids. That behavior comes from the compound itself: Viton® (FKM) is known for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where ketones and esters or low-molecular-weight organic acids are present.
It sees regular use in semiconductor equipment, chemical processing, and automotive fuel systems.
VB75901 ships individually. Unit weight is approximately 0.0661 g. Check the compound against your process media, pressure and temperature before committing to a design.
