Q-152 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-152 black Viton® (FKM) 75 Shore A supplied with an inside diameter of 3.237 in (82.22 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.443 in (87.45 mm), catalogued under part number QV70152. It resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Viton® (FKM) delivers outstanding high-temperature capability, excellent resistance to compression set and permeation. The compound resists aggressive chemicals, chlorinated solvents, and engine and transmission fluids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or hot water and steam. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

Maintenance and OEM teams specify it across oil and gas, automotive fuel systems, and high-temperature process equipment.

Reference part number QV70152 when ordering; the item is sold individually. Unit weight is approximately 2.7438 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
