Product Specification

-
The H3X176 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 176 mm (6.929 in), a cross section of 3 mm (0.118 in), and an outside diameter of 182 mm (7.17 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is widely chosen for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. This material stands up to many alcohols, propane and butane, and hydraulic fluids. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or polar solvents.

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

Stocked as H3X176 and sold individually. Unit weight is approximately 5.19 g. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
