An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) is valued for low compression set under sustained load, strong abrasion and tear resistance. It resists greases and lubricants, hydraulic fluids, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or ketones will shorten service life.
