Q-134 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-134 black Viton® (FKM) 75 Shore A 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. The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

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.
