4116-366Y MINNESOTA RUBBER QUAD RING

Part number HQ4116 is an AS568-116 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 0.737 in (18.72 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.943 in (23.95 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, low compression set under sustained load. The material holds up against water, petroleum-based oils, and propane and butane. 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 a parting line located away from the sealing surface.

You will find this material specified across automotive, construction equipment, and fluid power.
