Part number QV70315 is an AS568-315 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 0.787 in (19.99 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.207 in (30.66 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.
Viton® (FKM) is known for very low compression set at elevated temperature and outstanding high-temperature capability. The compound resists chlorinated solvents, engine and transmission fluids, and many acids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where amines or ketones and esters are present. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.
Common environments for this compound include oil and gas, automotive fuel systems, and aerospace.
This item is sold individually under part number QV70315. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
