3.5MM CS X 76MM ID BLACK BUNA 70D

The H3.5X76 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 76 mm (2.992 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 83 mm (3.27 in). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is specified for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. The material holds up against propane and butane, greases and lubricants, and many alcohols. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving automotive brake fluid or strong acids call for a different compound.

Common environments for this compound include construction equipment, agricultural equipment, and hydraulic and pneumatic systems.

H3.5X76 ships individually. Unit weight is approximately 3.11 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
