4154-366Y MINNESOTA RUBBER QUAD RING

APG stocks the HQ4154, an AS568-154 black Buna-N (Nitrile) 70 Shore A Quad-Ring measuring an inside diameter of 3.737 in (94.92 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.943 in (100.15 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Buna-N (Nitrile) is specified here for low compression set under sustained load, strong abrasion and tear resistance. The material holds up against propane and butane, many alcohols, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or ozone and direct sunlight call for a different compound. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

Common environments for this compound include hydraulic and pneumatic systems, automotive, and fluid power.

HQ4154 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
