Q-232 FLUOROELASTOMER 75 Q RING

Part number QV70232 is an AS568-232 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 2.734 in (69.44 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.012 in (76.5 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. The material holds up against aromatic hydrocarbons, aggressive chemicals, and engine and transmission fluids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or ketones and esters. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

It sees regular use in chemical processing, aerospace, and automotive fuel systems.
