QV70210 is an AS568-210 black Viton® (FKM) 75 Shore A quad profile Quad-Ring measuring an inside diameter of 0.734 in (18.64 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.012 in (25.7 mm). In service, this quad-ring provides a dual sealing band on each contact face for improved reliability.
It resists engine and transmission fluids, aggressive chemicals, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is specified for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.
Maintenance and OEM teams specify it across aerospace, oil and gas, and automotive fuel systems.
Stocked as QV70210 and sold individually. Unit weight is approximately 1.3798 g. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
