-393 BLUE FKM 75D O-RING

The V75MD393 is an AS568-393 blue Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 23.94 in (608.08 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 24.36 in (618.74 mm). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and industry benchmark where nitrile reaches its thermal limit. The material holds up against chlorinated solvents, many acids, and engine and transmission fluids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or amines will shorten service life.

The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across high-temperature process equipment, chemical processing, and aerospace.
