Buna-N (Nitrile) is known for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. This material stands up to many alcohols, water, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It should not be specified for service in automotive brake fluid or ketones.

Common environments for this compound include fluid power, hydraulic and pneumatic systems, and agricultural equipment.

H5X4 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
