3.55MM CS X 26.5MM ID BLACK BUNA 70D

The H3.55X26.5 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 26.5 mm (1.043 in), a cross section of 3.55 mm (0.14 in), and an outside diameter of 33.6 mm (1.32 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) is specified for strong abrasion and tear resistance, low compression set under sustained load. It resists propane and butane, water, and many alcohols. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or polar solvents will shorten service life.

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

Stocked as H3.55X26.5 and sold individually. Unit weight is approximately 1.195 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
