Q-031 FLUOROELASTOMER 75 Q RING

QV70031 is an AS568-031 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 1.739 in (44.17 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.879 in (47.73 mm). In service, this quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

The material holds up against many acids, aromatic hydrocarbons, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in hot water and steam or low-molecular-weight organic acids. The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

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

QV70031 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
