4374-514AD MINNESOTA RUBBER QUAD RING

APG stocks the VQ4374, an AS568-374 black Viton® (FKM) 75 Shore A quad profile Quad-Ring measuring an inside diameter of 9.984 in (253.59 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.645 in (244.98 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

This material stands up to many acids, engine and transmission fluids, and aromatic hydrocarbons. Viton® (FKM) is known for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in hot water and steam or ketones and esters.

You will find this material specified across aerospace, automotive fuel systems, and oil and gas.

VQ4374 ships individually. Nominal inside diameter is listed as 9 1/4. As always, verify media compatibility and operating conditions against the requirements of your specific application.
