-120 BLACK FKM 75D O-RING

The V75120 is an AS568-120 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 0.987 in (25.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.193 in (30.3 mm). This 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 and outstanding high-temperature capability. It resists engine and transmission fluids, aromatic hydrocarbons, and petroleum oils and fuels. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

Maintenance and OEM teams specify it across aerospace, semiconductor equipment, and chemical processing.

Stocked as V75120 and sold individually. Unit weight is approximately 0.87 g and nominal inside diameter is listed as 1 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
