1.2MM CS X 35MM ID BLACK BUNA 70D

H1.2X35 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 35 mm (1.378 in), a cross section of 1.2 mm (0.047 in), and an outside diameter of 37.4 mm (1.47 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs and most widely specified general-purpose sealing elastomer. The material holds up against hydraulic fluids, water, and petroleum-based oils. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or strong acids call for a different compound.

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

H1.2X35 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
