568-047 FKM 75 SQUARE CUT RINGS

APG stocks the SV70047, an AS568-047 black Viton® (FKM) 70 Shore A square profile Quad-Ring measuring an inside diameter of 4.489 in (114.02 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 4.629 in (117.58 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

The material holds up against aromatic hydrocarbons, chlorinated solvents, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) delivers very low compression set at elevated temperature and outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in hot water and steam or ketones and esters.

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

Stocked as SV70047 and sold individually. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
