568-135 FKM 75 SQUARE CUT RINGS

SV70135 is an AS568-135 black Viton® (FKM) 70 Shore A square profile Quad-Ring with an inside diameter of 1.925 in (48.9 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.131 in (54.13 mm). In service, this quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

As a material, Viton® (FKM) delivers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Expect good resistance to chlorinated solvents, many acids, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving low-molecular-weight organic acids or amines call for a different compound.

Common environments for this compound include chemical processing, semiconductor equipment, and oil and gas.

This item is sold individually under part number SV70135. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
