Q-237 FLUOROELASTOMER 75 Q RING

Part number QV70237 is an AS568-237 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 3.359 in (85.32 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.637 in (92.38 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

The material holds up against aggressive chemicals, aromatic hydrocarbons, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is valued for outstanding high-temperature capability, excellent resistance to compression set and permeation. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with ketones and esters or hot water and steam. The profile itself contributes two sealing bands per contact face rather than one and resistance to the spiral twisting that defeats round-section rings.

It sees regular use in automotive fuel systems, oil and gas, and high-temperature process equipment.

QV70237 ships individually. Unit weight is approximately 5.2843 g and nominal inside diameter is listed as 3 3/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
