*4328-514AD MINNESOTA RUBBER QUAD RING

The VQ4328 is an AS568-328 black Viton® (FKM) 75 Shore A quad profile Quad-Ring built to an inside diameter of 1.85 in (46.99 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.27 in (57.66 mm). This quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

As a material, Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Expect good resistance to aromatic hydrocarbons, many acids, and aggressive chemicals. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to hot water and steam or amines will shorten service life.

You will find this material specified across automotive fuel systems, high-temperature process equipment, and semiconductor equipment.
