*4336-514AD MINNESOTA RUBBER QUAD RING

The VQ4336 is an AS568-336 black Viton® (FKM) 75 Shore A quad profile Quad-Ring supplied with an inside diameter of 2.85 in (72.39 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.27 in (83.06 mm). This quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

It resists many acids, aromatic hydrocarbons, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is valued for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or hot water and steam call for a different compound.

Typical settings include chemical processing, oil and gas, and aerospace.

This item is sold individually under part number VQ4336. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
