Q-333 FLUOROELASTOMER 75 Q RING

The QV70333 is an AS568-333 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 2.475 in (62.87 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.895 in (73.53 mm). This quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) is specified here for excellent resistance to compression set and permeation, very low compression set at elevated temperature. The material holds up against aromatic hydrocarbons, petroleum oils and fuels, and engine and transmission fluids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

Maintenance and OEM teams specify it across automotive fuel systems, semiconductor equipment, and aerospace.
