-471 BLACK FKM 75D O-RING

V70471 is an AS568-471 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 21.955 in (557.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 22.505 in (571.63 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against aggressive chemicals, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) offers outstanding high-temperature capability, excellent resistance to compression set and permeation. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where hot water and steam or low-molecular-weight organic acids are present.

Maintenance and OEM teams specify it across oil and gas, automotive fuel systems, and high-temperature process equipment.
