The VITON75177 is an AS568-177 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 9.487 in (240.97 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.693 in (246.2 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The material holds up against engine and transmission fluids, chlorinated solvents, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).
Maintenance and OEM teams specify it across aerospace, high-temperature process equipment, and chemical processing.
Stocked as VITON75177 and sold individually. Unit weight is approximately 7.4982 g and nominal inside diameter is listed as 9 1/2 inch. Review your operating media and conditions against this specification before installation.
