*4110-366Y MINNESOTA RUBBER QUAD RING

Part number HQ4110 is an AS568-110 black Buna-N (Nitrile) 70 Shore A Quad-Ring measuring an inside diameter of 0.362 in (9.19 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.568 in (14.43 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, strong abrasion and tear resistance. Expect good resistance to hydraulic fluids, greases and lubricants, and propane and butane. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving polar solvents or ozone and direct sunlight call for a different compound. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

It sees regular use in general industrial maintenance, agricultural equipment, and fluid power.

HQ4110 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
