The flow/return pipe grommet is a protective rubber or plastic component used where pipes pass through boiler casings or walls. It cushions the pipe, reduces vibration, and prevents metal-to-metal contact. This grommet also helps seal the opening against drafts and debris. Essential for proper installation and maintenance, it contributes to the longevity of your heating system.
