Q-341 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-341 black Viton® (FKM) 75 Shore A quad profile built to an inside diameter of 3.475 in (88.27 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.895 in (98.93 mm), catalogued under part number QV70341. It seats in a standard o-ring gland while offering improved dynamic performance.

It resists engine and transmission fluids, chlorinated solvents, and many acids. That behavior comes from the compound itself: Viton® (FKM) is known for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or low-molecular-weight organic acids call for a different compound.

Common environments for this compound include semiconductor equipment, oil and gas, and chemical processing.

This item is sold individually under part number QV70341. Unit weight is approximately 13.702 g and nominal inside diameter is listed as 3 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
