-165 BLACK FKM 75D O-RING

Ordered as V75165, this is an AS568-165 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 6.487 in (164.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.693 in (170 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to petroleum oils and fuels, many acids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is valued for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in hot water and steam or low-molecular-weight organic acids.

Common environments for this compound include chemical processing, automotive fuel systems, and oil and gas.

V75165 ships individually. Nominal inside diameter is listed as 6 1/2 inch. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
