Q-252 FLUOROELASTOMER 75 Q RING

The QV70252 is an AS568-252 black Viton® (FKM) 75 Shore A quad profile Quad-Ring measuring an inside diameter of 5.234 in (132.94 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.512 in (140 mm). This quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

The compound resists engine and transmission fluids, aromatic hydrocarbons, and petroleum oils and fuels. Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.

It sees regular use in oil and gas, semiconductor equipment, and automotive fuel systems.

QV70252 ships individually. Unit weight is approximately 8.625 g and nominal inside diameter is listed as 5 1/4 inch. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
