*4264-514AD MINNESOTA RUBBER QUAD RING

APG stocks the VQ4264, an AS568-264 black Viton® (FKM) 75 Shore A quad profile Quad-Ring built to an inside diameter of 7.484 in (190.09 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 7.762 in (197.15 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

The material holds up against petroleum oils and fuels, many acids, and engine and transmission fluids. Viton® (FKM) is specified for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C).

Maintenance and OEM teams specify it across semiconductor equipment, automotive fuel systems, and chemical processing.
