*4252-514AD MINNESOTA RUBBER QUAD RING

Part number VQ4252 is an AS568-252 black Viton® (FKM) 75 Shore A Quad-Ring built to 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). A quad-ring provides a dual sealing band on each contact face for improved reliability.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. It resists engine and transmission fluids, many acids, and chlorinated solvents. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). 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 oil and gas, chemical processing, and aerospace.
