Q-254 FLUOROELASTOMER 75 Q RING

Part number QV70254 is an AS568-254 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 5.484 in (139.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.762 in (146.35 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

As a material, Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, outstanding high-temperature capability. It resists aromatic hydrocarbons, many acids, and aggressive chemicals. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines 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.

You will find this material specified across oil and gas, automotive fuel systems, and chemical processing.

QV70254 ships individually. Unit weight is approximately 8.6813 g and nominal inside diameter is listed as 5 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design.
