Q-126 FLUOROELASTOMER 75 Q RING

Ordered as QV70126, this is an AS568-126 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 1.362 in (34.59 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.568 in (39.83 mm). The quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Viton® (FKM) offers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Expect good resistance to petroleum oils and fuels, many acids, and chlorinated solvents. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where hot water and steam or amines are present. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

You will find this material specified across semiconductor equipment, chemical processing, and oil and gas.
