Product Specification

-
The V90371 is an AS568-371 black Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 8.475 in (215.27 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 8.895 in (225.93 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Viton® (FKM) offers excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. The compound resists aggressive chemicals, chlorinated solvents, and petroleum oils and fuels. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in hot water and steam or ketones and esters.

It sees regular use in oil and gas, semiconductor equipment, and high-temperature process equipment.

V90371 ships individually. Unit weight is approximately 28.534 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
