4225-366Y MINNESOTA RUBBER QUAD RING

Part number HQ4225 is an AS568-225 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 1.859 in (47.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.137 in (54.28 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

As a material, Buna-N (Nitrile) is specified for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. This material stands up to hydraulic fluids, water, and greases and lubricants. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or strong acids are present. The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

Common environments for this compound include construction equipment, fluid power, and agricultural equipment.

Stocked as HQ4225 and sold individually. Nominal inside diameter is listed as 1 7/8 inch. Review your operating media and conditions against this specification before installation.
