-365 BROWN FKM 75D O-RING

APG stocks the VB75365, an AS568-365 brown Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 6.975 in (177.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.395 in (187.83 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists engine and transmission fluids, many acids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit, 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). It should not be specified for service in hot water and steam or low-molecular-weight organic acids.

Common environments for this compound include oil and gas, automotive fuel systems, and high-temperature process equipment.
