Q-433 FLUOROELASTOMER 75 Q RING

QV70433 is an AS568-433 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 5.475 in (139.07 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 6.025 in (153.04 mm). In service, this quad-ring provides a dual sealing band on each contact face for improved reliability.

Viton® (FKM) is specified here for very low compression set at elevated temperature, excellent resistance to compression set and permeation. Expect good resistance to many acids, engine and transmission fluids, and petroleum oils and fuels. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or amines. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

It sees regular use in semiconductor equipment, chemical processing, and automotive fuel systems.

This item is sold individually under part number QV70433. Unit weight is approximately 35.55 g and nominal inside diameter is listed as 5 1/2 inch.
