4114-366Y MINNESOTA RUBBER QUAD RING

The HQ4114 is an AS568-114 black Buna-N (Nitrile) 70 Shore A Quad-Ring measuring an inside diameter of 0.612 in (15.54 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.818 in (20.78 mm). This quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Buna-N (Nitrile) offers reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. The material holds up against propane and butane, many alcohols, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with strong acids or ketones. The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

Common environments for this compound include construction equipment, general industrial maintenance, and agricultural equipment.

Stocked as HQ4114 and sold individually. Nominal inside diameter is listed as 5/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
