8MM CS X 114MM ID BLACK BUNA 70D

Part number H8X114 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 114 mm (4.488 in), a cross section of 8 mm (0.315 in), and an outside diameter of 130 mm (5.12 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists water, greases and lubricants, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) delivers an economical choice for high-volume maintenance programs and low compression set under sustained load. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or ozone and direct sunlight will shorten service life.

Typical settings include fluid power, construction equipment, and hydraulic and pneumatic systems.

This item is sold individually under part number H8X114. Unit weight is approximately 23.11 g. Review your operating media and conditions against this specification before installation.
