*Q-150 FLUOROELASTOMER 75 Q RING

Part number QV70150 is an AS568-150 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 2.862 in (72.69 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.068 in (77.93 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. The material holds up against engine and transmission fluids, aggressive chemicals, and aromatic hydrocarbons. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with amines or ketones and esters. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.

Maintenance and OEM teams specify it across semiconductor equipment, oil and gas, and aerospace.

Reference part number QV70150 when ordering; the item is sold individually. Nominal inside diameter is listed as 2 7/8 inch. Review your operating media and conditions against this specification before installation.
