Q-011 FLUOROELASTOMER 75 Q RING

Part number QV70011 is an AS568-011 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 0.301 in (7.65 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.441 in (11.2 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) offers very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The material holds up against petroleum oils and fuels, chlorinated solvents, and engine and transmission fluids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.

Common environments for this compound include chemical processing, semiconductor equipment, and oil and gas.

Stocked as QV70011 and sold individually. Unit weight is approximately 0.1593 g and nominal inside diameter is listed as 5/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
