-904 BLUE FKM 75D O-RING

Part number V75MD904 is an AS568-904 blue Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 0.351 in (8.92 mm), a cross section of 0.072 in (1.83 mm), and an outside diameter of 0.495 in (12.57 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. The compound resists petroleum oils and fuels, engine and transmission fluids, and aromatic hydrocarbons. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines or hot water and steam.

This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. You will find this material specified across aerospace, automotive fuel systems, and chemical processing.

V75MD904 ships individually. Nominal inside diameter is listed as 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
