*Q-367 FLUOROELASTOMER 75 Q RING

QV70367 is an AS568-367 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 7.475 in (189.87 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.895 in (200.53 mm). In service, this quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Viton® (FKM) offers very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Expect good resistance to chlorinated solvents, aromatic hydrocarbons, and petroleum oils and fuels. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to ketones and esters or low-molecular-weight organic acids will shorten service life. The profile itself contributes a parting line located away from the sealing surface and resistance to the spiral twisting that defeats round-section rings.

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

This item is sold individually under part number QV70367. Nominal inside diameter is listed as 7 1/2 inch.
