Q-387 FLUOROELASTOMER 75 Q RING

Part number QV70387 is an AS568-387 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 17.955 in (456.06 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 18.375 in (466.73 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

As a material, Viton® (FKM) is known for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. It resists aromatic hydrocarbons, chlorinated solvents, and engine and transmission fluids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in ketones and esters or low-molecular-weight organic acids. The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

You will find this material specified across oil and gas, semiconductor equipment, and aerospace.

This item is sold individually under part number QV70387. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
