-377 BLACK FKM 75D O-RING

Ordered as V75377, this is an AS568-377 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 9.975 in (253.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.395 in (264.03 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to chlorinated solvents, aggressive chemicals, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for long service life in hot, chemically aggressive environments and outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in hot water and steam or amines.

Maintenance and OEM teams specify it across oil and gas, chemical processing, and automotive fuel systems.
