-170 BLACK FKM 90D O-RING

APG stocks the V90170, an AS568-170 black Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 7.737 in (196.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.943 in (201.75 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Viton® (FKM) delivers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. The material holds up against engine and transmission fluids, petroleum oils and fuels, and aromatic hydrocarbons. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where ketones and esters or amines are present.

You will find this material specified across automotive fuel systems, high-temperature process equipment, and oil and gas.

Reference part number V90170 when ordering; the item is sold individually. Unit weight is approximately 6.0608 g and nominal inside diameter is listed as 7 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
