Q-243 FLUOROELASTOMER 75 Q RING

Part number QV70243 is an AS568-243 black Viton® (FKM) 75 Shore A quad profile Quad-Ring measuring an inside diameter of 4.109 in (104.37 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.387 in (111.43 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

The material holds up against petroleum oils and fuels, chlorinated solvents, and aggressive chemicals. Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit 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 ketones and esters or amines will shorten service life.

It sees regular use in semiconductor equipment, aerospace, and high-temperature process equipment.
