4.5MM CS X 250MM ID BLACK FKM 75D

V4.5X250 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 250 mm (9.843 in), a cross section of 4.5 mm (0.177 in), and an outside diameter of 259 mm (10.2 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to chlorinated solvents, aggressive chemicals, and engine and transmission fluids. Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or hot water and steam will shorten service life.

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

V4.5X250 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
