*4029-366Y MINNESOTA RUBBER QUAD RING

This quad-ring is supplied in AS568-029 black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 1.489 in (37.82 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.629 in (41.38 mm), catalogued under part number HQ4029. It seats in a standard o-ring gland while offering improved dynamic performance.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, economical choice for high-volume maintenance programs. The compound resists many alcohols, petroleum-based oils, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with strong acids or automotive brake fluid. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

Typical settings include construction equipment, automotive, and hydraulic and pneumatic systems.

Stocked as HQ4029 and sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
