-165 BLACK FKM 75D O-RING

Part number V70165 is an AS568-165 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 6.487 in (164.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.693 in (170 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against many acids, petroleum oils and fuels, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is valued for very low compression set at elevated temperature, excellent resistance to compression set and permeation. 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 ketones and esters call for a different compound.

Maintenance and OEM teams specify it across semiconductor equipment, oil and gas, and chemical processing.
