Q-026 FLUOROELASTOMER 75 Q RING

This quad-ring is supplied in AS568-026 black Viton® (FKM) 75 Shore A supplied with an inside diameter of 1.239 in (31.47 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.379 in (35.03 mm), catalogued under part number QV70026. It delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) is specified here for very low compression set at elevated temperature and industry benchmark where nitrile reaches its thermal limit. This material stands up to aromatic hydrocarbons, aggressive chemicals, and engine and transmission fluids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

Maintenance and OEM teams specify it across oil and gas, high-temperature process equipment, and automotive fuel systems.

Order part number QV70026, sold individually. Unit weight is approximately 0.49 g and nominal inside diameter is listed as 1 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
