**4130-366Y MINNESOTA RUBBER QUAD RING

Part number HQ4130 is an AS568-130 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 1.612 in (40.94 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.818 in (46.18 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.

The material holds up against many alcohols, propane and butane, and greases and lubricants. Buna-N (Nitrile) is widely chosen for low compression set under sustained load, reliable performance in both static and dynamic service. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or polar solvents will shorten service life. The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

It sees regular use in construction equipment, fluid power, and agricultural equipment.
