This material stands up to many alcohols, water, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is known for an economical choice for high-volume maintenance programs and low compression set under sustained load. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ozone and direct sunlight or polar solvents.

Typical settings include agricultural equipment, automotive, and construction equipment.

H2X38.5 ships individually. Unit weight is approximately 0.5125 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
