BDM pellet pipe - gasket maintenance?

[Lake Girl]

We have BDM exhaust piping with the silicone gaskets. Just curious on how often silicone gaskets need to be replaced. Found the manufacturer info on line and has replacement gaskets but no mention on the typical life span.

Would like to stay ahead of the curve on maintenance rather than learn the hard way...

I'd say it depends upon how hard you are on them when removing and then reconnecting sections of vent. They should be impervious to everything except getting sliced and diced by sharp vent pipe ends. Maybe keep a spare on hand.
