*4103-366Y MINNESOTA RUBBER QUAD RING

Ordered as HQ4103, this is an AS568-103 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 0.081 in (2.06 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.287 in (7.29 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Buna-N (Nitrile) is specified for strong abrasion and tear resistance, reliable performance in both static and dynamic service. This material stands up to 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 resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

Typical settings include fluid power, hydraulic and pneumatic systems, and construction equipment.

Reference part number HQ4103 when ordering; the item is sold individually. Nominal inside diameter is listed as 3/32 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
