Q-120 BUNA 70 Q RING

This quad-ring is supplied in AS568-120 black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 0.987 in (25.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.193 in (30.3 mm), catalogued under part number QH70120. It provides a dual sealing band on each contact face for improved reliability.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, economical choice for high-volume maintenance programs. It resists propane and butane, hydraulic fluids, and water. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with ozone and direct sunlight or automotive brake fluid. The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

You will find this material specified across hydraulic and pneumatic systems, fluid power, and construction equipment.

This item is sold individually under part number QH70120. Unit weight is approximately 0.5538 g. Check the compound against your process media, pressure and temperature before committing to a design.
