Q-282 FLUOROELASTOMER 75 Q RING

Part number QV70282 is an AS568-282 black Viton® (FKM) 75 Shore A quad profile Quad-Ring supplied with an inside diameter of 15.955 in (405.26 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 16.233 in (412.32 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Viton® (FKM) is specified here for outstanding high-temperature capability and industry benchmark where nitrile reaches its thermal limit. It resists engine and transmission fluids, aromatic hydrocarbons, and many acids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in ketones and esters or amines.

Maintenance and OEM teams specify it across aerospace, automotive fuel systems, and semiconductor equipment.
