Buna 70-3mmCSx25mmID-Black-Pk50

Part number SB-H3X25-50 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 25 mm (0.984 in), a cross section of 3 mm (0.118 in), and an outside diameter of 31 mm (1.22 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. The catalog record notes: 25MMIDX3MMCS.

Buna-N (Nitrile) delivers low compression set under sustained load and the most widely specified general-purpose sealing elastomer. The material holds up against hydraulic fluids, propane and butane, and greases and lubricants. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or polar solvents will shorten service life.

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

SB-H3X25-50 ships by the bag. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
