Q-106 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-106 black Viton® (FKM) 75 Shore A built to an inside diameter of 0.174 in (4.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.38 in (9.65 mm), catalogued under part number QV70106. It seats in a standard o-ring gland while offering improved dynamic performance.

As a material, Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. It resists engine and transmission fluids, aromatic hydrocarbons, and many acids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or hot water and steam. The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

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

Order part number QV70106, sold individually. Nominal inside diameter is listed as 3/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
