4MM CS X 148MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 148 mm (5.827 in), a cross section of 4 mm (0.157 in), and an outside diameter of 156 mm (6.14 in), catalogued under part number H4X148. It creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and low compression set under sustained load. Expect good resistance to many alcohols, petroleum-based oils, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where polar solvents or strong acids are present.

Typical settings include construction equipment, hydraulic and pneumatic systems, and fluid power.

H4X148 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
