Q-007 FLUOROELASTOMER 75 Q RING

The QV70007 is an AS568-007 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 0.145 in (3.68 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.285 in (7.24 mm). This quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

This material stands up to aromatic hydrocarbons, petroleum oils and fuels, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is specified for very low compression set at elevated temperature, excellent resistance to compression set and permeation. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. 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 semiconductor equipment, automotive fuel systems, and aerospace.

This item is sold individually under part number QV70007. Unit weight is approximately 0.083 g and nominal inside diameter is listed as 5/32 inch. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
