-411 BLACK FKM 75D O-RING

V75411 is an AS568-411 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 2.725 in (69.22 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.275 in (83.19 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Expect good resistance to engine and transmission fluids, aromatic hydrocarbons, and chlorinated solvents. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service.

Maintenance and OEM teams specify it across semiconductor equipment, automotive fuel systems, and aerospace.
