*Q-435 FLUOROELASTOMER 75 Q RING

The QV70435 is an AS568-435 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 5.725 in (145.42 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 6.275 in (159.39 mm). This quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and outstanding high-temperature capability. The material holds up against petroleum oils and fuels, aromatic hydrocarbons, and aggressive chemicals. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes resistance to the spiral twisting that defeats round-section rings and a parting line located away from the sealing surface.

Typical settings include chemical processing, semiconductor equipment, and high-temperature process equipment.

This item is sold individually under part number QV70435. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
