-443 BLACK FKM 75D O-RING

The V75443 is an AS568-443 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 7.475 in (189.87 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 8.025 in (203.84 mm). 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 many acids. Viton® (FKM) offers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to hot water and steam or amines will shorten service life.

Common environments for this compound include automotive fuel systems, high-temperature process equipment, and aerospace.

This item is sold individually under part number V75443. Nominal inside diameter is listed as 7 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
