568-270 FKM 75 SQUARE CUT RINGS

APG stocks the SV70270, an AS568-270 black Viton® (FKM) 70 Shore A square profile Quad-Ring with an inside diameter of 8.984 in (228.19 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.262 in (235.25 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Expect good resistance to chlorinated solvents, engine and transmission fluids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is valued for excellent resistance to compression set and permeation, very low compression set at elevated temperature. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C).

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

SV70270 ships individually. Nominal inside diameter is listed as 9 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
