5.3MM CS X 41.2MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A measuring an inside diameter of 41.2 mm (1.622 in), a cross section of 5.3 mm (0.209 in), and an outside diameter of 51.8 mm (2.04 in), catalogued under part number H5.3X41.2. It compresses into its gland to block fluid or gas migration across a joint.

It resists propane and butane, many alcohols, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) offers strong abrasion and tear resistance, low compression set under sustained load. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or automotive brake fluid are present.

Typical settings include automotive, hydraulic and pneumatic systems, and agricultural equipment.

H5.3X41.2 ships individually. Unit weight is approximately 4.0754 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
