Q-111 FLUOROELASTOMER 75 Q RING

Part number QV70111 is an AS568-111 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 0.424 in (10.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.63 in (16 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.

Viton® (FKM) is known for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. The compound resists petroleum oils and fuels, chlorinated solvents, and many acids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or hot water and steam. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

Typical settings include aerospace, chemical processing, and semiconductor equipment.

Reference part number QV70111 when ordering; the item is sold individually. Unit weight is approximately 0.4482 g and nominal inside diameter is listed as 7/16 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
