Q-108 FLUOROELASTOMER 75 Q RING

Part number QV70108 is an AS568-108 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 0.237 in (6.02 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.443 in (11.25 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and industry benchmark where nitrile reaches its thermal limit. Expect good resistance to many acids, aromatic hydrocarbons, and engine and transmission fluids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or hot water and steam will shorten service life. The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

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