-128 BROWN FKM 90D O-RING

VB90128 is an AS568-128 brown Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 1.487 in (37.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.693 in (43 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to engine and transmission fluids, many acids, and chlorinated solvents. Viton® (FKM) is known for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or amines call for a different compound.

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

Stocked as VB90128 and sold individually. Unit weight is approximately 1.5441 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
