-400 BLACK FKM 75D O-RING

Part number V75400 is an AS568-400 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 1.35 in (34.29 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 1.9 in (48.26 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Viton® (FKM) is valued for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. The material holds up against petroleum oils and fuels, aggressive chemicals, and engine and transmission fluids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where hot water and steam or ketones and esters are present.

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