4434-366Y MINNESOTA RUBBER QUAD RING

Ordered as HQ4434, this is an AS568-434 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 5.6 in (142.24 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 6.15 in (156.21 mm). The quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) offers strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. This material stands up to many alcohols, water, and hydraulic fluids. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It should not be specified for service in strong acids or ozone and direct sunlight. The profile itself contributes two sealing bands per contact face rather than one and resistance to the spiral twisting that defeats round-section rings.

Typical settings include general industrial maintenance, agricultural equipment, and fluid power.
