*4104-366Y MINNESOTA RUBBER QUAD RING

This quad-ring is supplied in AS568-104 black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 0.112 in (2.84 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.318 in (8.08 mm), catalogued under part number HQ4104. It uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

The material holds up against many alcohols, hydraulic fluids, and propane and butane. Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or automotive brake fluid 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.

Common environments for this compound include construction equipment, general industrial maintenance, and hydraulic and pneumatic systems.

HQ4104 ships individually. Nominal inside diameter is listed as 1/8 inch. Review your operating media and conditions against this specification before installation.
