It provides a dual sealing band on each contact face for improved reliability.

This material stands up to propane and butane, water, and greases and lubricants. Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C).
