Q-240 FLUOROELASTOMER 75 Q RING

The QV70240 is an AS568-240 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 3.734 in (94.84 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.012 in (101.9 mm). This quad-ring provides a dual sealing band on each contact face for improved reliability.

As a material, Viton® (FKM) offers very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The compound resists many acids, aromatic hydrocarbons, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. The profile itself contributes lower compressive load required to achieve a seal and resistance to the spiral twisting that defeats round-section rings.

You will find this material specified across semiconductor equipment, automotive fuel systems, and aerospace.
