5MM CS X 76MM ID BLACK BUNA 70D

The H5X76 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 76 mm (2.992 in), a cross section of 5 mm (0.197 in), and an outside diameter of 86 mm (3.39 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs, strong abrasion and tear resistance. This material stands up to greases and lubricants, petroleum-based oils, and propane and butane. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to automotive brake fluid or strong acids will shorten service life.

Maintenance and OEM teams specify it across fluid power, construction equipment, and automotive.
