Q-136 FLUOROELASTOMER 75 Q RING

QV70136 is an AS568-136 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 1.987 in (50.47 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.193 in (55.7 mm). In service, this quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

The compound resists petroleum oils and fuels, engine and transmission fluids, and aggressive chemicals. Viton® (FKM) offers very low compression set at elevated temperature and outstanding high-temperature capability. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life. The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

Maintenance and OEM teams specify it across aerospace, semiconductor equipment, and chemical processing.
