Product Specification

-
This quad-ring is supplied in AS568-323 black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 1.287 in (32.69 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.707 in (43.36 mm), catalogued under part number HQ4323. It provides a dual sealing band on each contact face for improved reliability.

Buna-N (Nitrile) is valued for low compression set under sustained load, reliable performance in both static and dynamic service. The compound resists propane and butane, many alcohols, and petroleum-based oils. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

Typical settings include general industrial maintenance, hydraulic and pneumatic systems, and fluid power.

Order part number HQ4323, sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
