-220 BROWN FKM 90D O-RING

VB90220 is an AS568-220 brown Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 1.359 in (34.52 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.637 in (41.58 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Viton® (FKM) is specified for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. It resists petroleum oils and fuels, aggressive chemicals, and chlorinated solvents. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or amines.

Common environments for this compound include oil and gas, aerospace, and high-temperature process equipment.
