*4334-514AD MINNESOTA RUBBER QUAD RING

The VQ4334 is an AS568-334 black Viton® (FKM) 75 Shore A quad profile Quad-Ring with an inside diameter of 2.6 in (66.04 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.02 in (76.71 mm). This quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

It resists chlorinated solvents, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) offers long service life in hot, chemically aggressive environments and outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

Maintenance and OEM teams specify it across aerospace, chemical processing, and oil and gas.
