568-312 FKM 75 SQUARE CUT RINGS

APG stocks the SV70312, an AS568-312 black Viton® (FKM) 70 Shore A square profile Quad-Ring with an inside diameter of 0.6 in (15.24 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.02 in (25.91 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

The material holds up against petroleum oils and fuels, engine and transmission fluids, and many acids. That behavior comes from the compound itself: Viton® (FKM) offers very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service.

Maintenance and OEM teams specify it across chemical processing, aerospace, and automotive fuel systems.

Order part number SV70312, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
