4265-514AD MINNESOTA RUBBER QUAD RING

Part number VQ4265 is an AS568-265 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 7.734 in (196.44 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.012 in (203.5 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

This material stands up to aggressive chemicals, petroleum oils and fuels, and aromatic hydrocarbons. Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

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