Q-377 FLUOROELASTOMER 75 Q RING

Ordered as QV70377, this is an AS568-377 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 9.975 in (253.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.395 in (264.03 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. Expect good resistance to aromatic hydrocarbons, aggressive chemicals, and many acids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with ketones and esters or amines. 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, automotive fuel systems, and chemical processing.

This item is sold individually under part number QV70377. Unit weight is approximately 23.697 g and nominal inside diameter is listed as 10 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
