Buna-N Rubber Grommets

The purpose of any grommet is to reinforce a hole. Buna N Rubber is a particularly non-absorbent, strong, less flexible rubber that is resistant to chemicals, oil and water, but should not be used with acids, synthetic lubricants, or in high-temperature environments. Therefore, Buna-N rubber grommets should be used to reinforce holes in systems where chemicals, oil and water are present, but not in high temperature systems or systems that involve acids or synthetic lubricants. For more on synthetic rubber, see our silicone rubber grommets.
