Buna 70-2mmCSx30mmID-Black-Pk50

The SB-H2X30-50 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 30 mm (1.181 in), a cross section of 2 mm (0.079 in), and an outside diameter of 34 mm (1.34 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. This item is further identified as 30MMIDX2MMCS.

As a material, Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. The compound resists many alcohols, hydraulic fluids, and greases and lubricants. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C).

Maintenance and OEM teams specify it across general industrial maintenance, agricultural equipment, and hydraulic and pneumatic systems.
