-350 BLACK FKM 75D O-RING

Ordered as V70350, this is an AS568-350 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 4.6 in (116.84 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.02 in (127.51 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against many acids, chlorinated solvents, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) delivers excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to amines or low-molecular-weight organic acids will shorten service life.

Maintenance and OEM teams specify it across automotive fuel systems, high-temperature process equipment, and oil and gas.
