Q-330 FLUOROELASTOMER 75 Q RING

Ordered as QV70330, this is an AS568-330 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 2.1 in (53.34 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.52 in (64.01 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) offers very low compression set at elevated temperature and outstanding high-temperature capability. The compound resists many acids, engine and transmission fluids, and chlorinated solvents. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes a parting line located away from the sealing surface and resistance to the spiral twisting that defeats round-section rings.

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

QV70330 ships individually. Unit weight is approximately 8.105 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
