The Portable Spa Anode (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. This anode can be installed on a 2 inch PVC flex pipe or a rigid 2 inch PVC pipe. It includes a flex PVC support fitting, bracket, and anode chamber.
