This o-ring is supplied in AS568-168 black Viton® (FKM) 75 Shore A measuring an inside diameter of 7.237 in (183.82 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.443 in (189.05 mm), catalogued under part number VITON75168. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. The material holds up against aromatic hydrocarbons, petroleum oils and fuels, and engine and transmission fluids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where low-molecular-weight organic acids or amines are present.
You will find this material specified across semiconductor equipment, aerospace, and chemical processing.
Stocked as VITON75168 and sold individually. Unit weight is approximately 5.93 g and nominal inside diameter is listed as 7 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
