Q-328 FLUOROELASTOMER 75 Q RING

The QV70328 is an AS568-328 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 1.85 in (46.99 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.27 in (57.66 mm). This quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

This material stands up to aromatic hydrocarbons, aggressive chemicals, and engine and transmission fluids. Viton® (FKM) delivers very low compression set at elevated temperature and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where ketones and esters or low-molecular-weight organic acids are present. The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

It sees regular use in oil and gas, chemical processing, and aerospace.

This item is sold individually under part number QV70328. Unit weight is approximately 7.24 g and nominal inside diameter is listed as 1 7/8 inch. Review your operating media and conditions against this specification before installation.
