The Spigot Portable Spa Anode (1-1/2 inch) is a zinc sacrificial anode that is designed to protect all metal parts (heater, pump, seal and shaft) against corrosion (electrolysis) in portable spas using a salt chlorine generator. The spigot allows the anode chamber to be glued onto a 1 inch tee.
Note: A 1-1/2 or 2 inch tee can be reduced to accept the 1 inch spigot.
