-283 BLACK FKM 75D O-RING

The V70283 is an AS568-283 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 16.955 in (430.66 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 17.233 in (437.72 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to petroleum oils and fuels, aromatic hydrocarbons, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) offers long service life in hot, chemically aggressive environments and outstanding high-temperature capability. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with hot water and steam or amines.

Maintenance and OEM teams specify it across automotive fuel systems, aerospace, and chemical processing.

V70283 ships individually. Unit weight is approximately 24.42 g and nominal inside diameter is listed as 17 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.
