-461 BROWN FKM 90D O-RING

This o-ring is supplied in AS568-461 brown Viton® (FKM) 90 Shore A with an inside diameter of 15.955 in (405.26 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 16.505 in (419.23 mm), catalogued under part number VB90461. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, outstanding high-temperature capability. Expect good resistance to engine and transmission fluids, chlorinated solvents, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where amines or low-molecular-weight organic acids are present.

You will find this material specified across automotive fuel systems, aerospace, and chemical processing.

VB90461 ships individually. Nominal inside diameter is listed as 16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
