568-325 FKM 75 SQUARE CUT RINGS

APG stocks the SV70325, an AS568-325 black Viton® (FKM) 70 Shore A square profile Quad-Ring built to an inside diameter of 1.475 in (37.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.895 in (48.13 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Expect good resistance to petroleum oils and fuels, many acids, and engine and transmission fluids. Viton® (FKM) delivers excellent resistance to compression set and permeation, outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life.

You will find this material specified across automotive fuel systems, chemical processing, and aerospace.

Stocked as SV70325 and sold individually. Nominal inside diameter is listed as 1 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
