4115-514AD MINNESOTA RUBBER QUAD RING

APG stocks the VQ4115, an AS568-115 black Viton® (FKM) 75 Shore A quad profile Quad-Ring measuring an inside diameter of 0.674 in (17.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.88 in (22.35 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. It resists many acids, aggressive chemicals, and aromatic hydrocarbons. 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 ketones and esters will shorten service life.

It sees regular use in chemical processing, high-temperature process equipment, and automotive fuel systems.
