Q-235 FLUOROELASTOMER 75 Q RING

Ordered as QV70235, this is an AS568-235 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 3.109 in (78.97 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.387 in (86.03 mm). The quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Expect good resistance to aggressive chemicals, aromatic hydrocarbons, and engine and transmission fluids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.

You will find this material specified across high-temperature process equipment, oil and gas, and aerospace.

This item is sold individually under part number QV70235. Unit weight is approximately 5.1566 g and nominal inside diameter is listed as 3 1/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
