Balboa 2″ Flanged Heater Gasket

This gasket fits almost all spa heaters made by Balboa (including those from the Lite Leader, GS, VS and M7 series) and whose ends connect with a 2″ FBT heater union. It fits perfectly with the brand’s 2″ split nut. If your hot tub heater is leaking at the unions, chances are you need to replace these gaskets.
