4115-366Y MINNESOTA RUBBER QUAD RING

Ordered as HQ4115, this is an AS568-115 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 0.674 in (17.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.88 in (22.35 mm). The quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring. The catalog record notes: NBR 70 Duro.

Buna-N (Nitrile) is specified for strong abrasion and tear resistance, reliable performance in both static and dynamic service. This material stands up to water, propane and butane, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It should not be specified for service in ozone and direct sunlight or automotive brake fluid. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.

You will find this material specified across hydraulic and pneumatic systems, fluid power, and general industrial maintenance.
