Northern Stainless In Line Anode Clear PVC 1" Diameter

The Northern Stainless In-Line Anode in Clear PVC is a critical preventative maintenance component designed to protect underwater metal hardware from the damaging effects of galvanic corrosion. Specifically engineered for 1-inch diameter plumbing lines, this unit features a transparent PVC housing that allows for easy visual inspection of the sacrificial zinc anode without the need to disassemble the filtration system. As water flows through the chamber, the integrated zinc core proactively attracts the electrolytic current that would otherwise cause pitting and oxidation on expensive stainless steel ladders, lights, and heaters, making it an essential addition for saltwater pool systems. The assembly includes a grounding wire and lug to ensure a proper electrical path for maximum effectiveness. Due to the high density of the solid sacrificial zinc rod housed within the compact, pressure-rated clear casing, the entire in-line unit weighs approximately 1.5 pounds, providing a lightweight yet powerful defense system that extends the lifespan of all metallic pool components.
