VQ4344 is an AS568-344 black Viton® (FKM) 75 Shore A quad profile Quad-Ring measuring an inside diameter of 3.85 in (97.79 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.27 in (108.46 mm). In service, this quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. It resists engine and transmission fluids, chlorinated solvents, and petroleum oils and fuels. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

Maintenance and OEM teams specify it across high-temperature process equipment, semiconductor equipment, and aerospace.
