Product Specification

-
This quad-ring is supplied in AS568-005 black Buna-N (Nitrile) 70 Shore A measuring an inside diameter of 0.101 in (2.57 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.241 in (6.12 mm), catalogued under part number HQ4005. It seats in a standard o-ring gland while offering improved dynamic performance.

As a material, Buna-N (Nitrile) is valued for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Expect good resistance to greases and lubricants, many alcohols, and petroleum-based oils. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ketones or ozone and direct sunlight. The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

It sees regular use in construction equipment, general industrial maintenance, and fluid power.

This item is sold individually under part number HQ4005. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
