*4432-366Y MINNESOTA RUBBER QUAD RING

Ordered as HQ4432, this is an AS568-432 black Buna-N (Nitrile) 70 Shore A Quad-Ring measuring an inside diameter of 5.35 in (135.89 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.9 in (149.86 mm). The quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Buna-N (Nitrile) delivers low compression set under sustained load, strong abrasion and tear resistance. This material stands up to greases and lubricants, water, and many alcohols. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

You will find this material specified across general industrial maintenance, construction equipment, and agricultural equipment.

Stocked as HQ4432 and sold individually. Nominal inside diameter is listed as 5 3/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
