Q-134 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-134 black Viton® (FKM) 75 Shore A quad profile measuring an inside diameter of 1.862 in (47.29 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.068 in (52.53 mm), catalogued under part number QV70134. It delivers lower friction and better sealing stability than a comparable round-section o-ring.

The material holds up against engine and transmission fluids, many acids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is known for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving ketones and esters or amines call for a different compound.

It sees regular use in semiconductor equipment, aerospace, and oil and gas.

This item is sold individually under part number QV70134. Unit weight is approximately 1.65 g and nominal inside diameter is listed as 1 7/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
