Q-219 FLUOROELASTOMER 75 Q RING

The QV70219 is an AS568-219 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 1.296 in (32.92 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.574 in (39.98 mm). This quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) is known for excellent resistance to compression set and permeation, very low compression set at elevated temperature. The compound resists chlorinated solvents, engine and transmission fluids, and aromatic hydrocarbons. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life. The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

It sees regular use in high-temperature process equipment, aerospace, and chemical processing.

This item is sold individually under part number QV70219. Unit weight is approximately 2.2687 g and nominal inside diameter is listed as 1 5/16 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
