-335 BLACK CHEMOURS VITON 75D O-RING

APG stocks the VITON75335, an AS568-335 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 2.725 in (69.22 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.145 in (79.88 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

It resists chlorinated solvents, petroleum oils and fuels, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is widely chosen 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). Exposure to ketones and esters or low-molecular-weight organic acids will shorten service life.

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