Q-153 BUNA 70 Q RING

The QH70153 is an AS568-153 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 3.487 in (88.57 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.693 in (93.8 mm). This quad-ring provides a dual sealing band on each contact face for improved reliability.

The material holds up against many alcohols, petroleum-based oils, and water. Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or strong acids 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.

Typical settings include fluid power, construction equipment, and automotive.

Order part number QH70153, sold individually. Unit weight is approximately 2.246 g and nominal inside diameter is listed as 3 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
