Q-238 FLUOROELASTOMER 75 Q RING

Part number QV70238 is an AS568-238 black Viton® (FKM) 75 Shore A quad profile Quad-Ring with an inside diameter of 3.484 in (88.49 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.762 in (95.55 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Expect good resistance to petroleum oils and fuels, engine and transmission fluids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is known for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life.

Typical settings include oil and gas, aerospace, and semiconductor equipment.

QV70238 ships individually. Unit weight is approximately 5.2396 g and nominal inside diameter is listed as 3 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
