2MM CS X 13MM ID BLACK BUNA 70D

H2X13 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 13 mm (0.512 in), a cross section of 2 mm (0.079 in), and an outside diameter of 17 mm (0.67 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against water, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

It sees regular use in fluid power, construction equipment, and automotive.
