*Q-268 FLUOROELASTOMER 75 Q RING

Part number QV70268 is an AS568-268 black Viton® (FKM) 75 Shore A quad profile Quad-Ring with an inside diameter of 8.484 in (215.49 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.762 in (222.55 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

This material stands up to many acids, petroleum oils and fuels, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.

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

QV70268 ships individually. Unit weight is approximately 13.632 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
