Product Specification

-
Ordered as H2X63, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 63 mm (2.48 in), a cross section of 2 mm (0.079 in), and an outside diameter of 67 mm (2.64 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against greases and lubricants, petroleum-based oils, and hydraulic fluids. Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and low compression set under sustained load. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C).

Typical settings include fluid power, general industrial maintenance, and hydraulic and pneumatic systems.

H2X63 ships individually. Unit weight is approximately 0.0009 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
