The QV70176 is an AS568-176 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 9.237 in (234.62 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.443 in (239.85 mm). This quad-ring seats in a standard o-ring gland while offering improved dynamic performance.
Expect good resistance to engine and transmission fluids, many acids, and aggressive chemicals. Viton® (FKM) offers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.
You will find this material specified across oil and gas, aerospace, and automotive fuel systems.
This item is sold individually under part number QV70176. Nominal inside diameter is listed as 9 1/4 inch. 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.
