APG stocks the VQ4452, an AS568-452 black Viton® (FKM) 75 Shore A quad profile Quad-Ring built to an inside diameter of 11.475 in (291.47 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 12.025 in (305.44 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. The compound resists aromatic hydrocarbons, petroleum oils and fuels, and many acids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with amines or ketones and esters.

Common environments for this compound include high-temperature process equipment, oil and gas, and semiconductor equipment.

Reference part number VQ4452 when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
