Product Specification

-
Part number HQ4426 is an AS568-426 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 4.6 in (116.84 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.15 in (130.81 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.

Buna-N (Nitrile) is specified here for most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. It resists water, hydraulic fluids, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to automotive brake fluid or ketones 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.

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

Order part number HQ4426, sold individually. Nominal inside diameter is listed as 4 5/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
