-406 BLACK CHEMOURS VITON 75D O-RING

Part number VITON75406 is an AS568-406 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 2.1 in (53.34 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.65 in (67.31 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to engine and transmission fluids, chlorinated solvents, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. 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 ketones and esters are present.

Common environments for this compound include aerospace, automotive fuel systems, and semiconductor equipment.
