*4465-366Y MINNESOTA RUBBER QUAD RING

HQ4465 is an AS568-465 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 17.955 in (456.06 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.505 in (470.03 mm). In service, this quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Expect good resistance to hydraulic fluids, many alcohols, and petroleum-based oils. Buna-N (Nitrile) delivers low compression set under sustained load, strong abrasion and tear resistance. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in polar solvents or strong acids. The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

Typical settings include automotive, construction equipment, and general industrial maintenance.

Stocked as HQ4465 and sold individually. Nominal inside diameter is listed as 18 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
