-161 BROWN FKM 90D O-RING

The VB90161 is an AS568-161 brown Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 5.487 in (139.37 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.693 in (144.6 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Expect good resistance to aggressive chemicals, many acids, and engine and transmission fluids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service.

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