Q-313 FLUOROELASTOMER 75 Q RING

The QV70313 is an AS568-313 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 0.662 in (16.81 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.082 in (27.48 mm). This quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

As a material, Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, very low compression set at elevated temperature. Expect good resistance to engine and transmission fluids, aggressive chemicals, and aromatic hydrocarbons. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where hot water and steam or ketones and esters are present. The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

You will find this material specified across semiconductor equipment, oil and gas, and high-temperature process equipment.

This item is sold individually under part number QV70313. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
