-348 BLACK CHEMOURS VITON 75D O-RING

VITON75348 is an AS568-348 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 4.35 in (110.49 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.77 in (121.16 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

As a material, Viton® (FKM) is known for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. The compound resists aggressive chemicals, engine and transmission fluids, and petroleum oils and fuels. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life.

It sees regular use in aerospace, automotive fuel systems, and high-temperature process equipment.

VITON75348 ships individually. Unit weight is approximately 14.933 g and nominal inside diameter is listed as 4 3/8 inch.
