4.5MM CS X 23MM ID BLACK BUNA 70D

The H4.5X23 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 23 mm (0.906 in), a cross section of 4.5 mm (0.177 in), and an outside diameter of 32 mm (1.26 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists propane and butane, many alcohols, and petroleum-based oils. Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C).

Maintenance and OEM teams specify it across fluid power, hydraulic and pneumatic systems, and agricultural equipment.

H4.5X23 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
