Tecnoseal SZ-1 Sea Strainer Anode - Zinc

The Tecnoseal SZ-1 Sea Strainer Anode – Zinc is an essential sacrificial protection component designed for marine cooling systems and through-hull strainers on saltwater vessels. It serves as a protective measure against galvanic corrosion, which can compromise the integrity of your engine and cooling system over time.

Constructed from marine-grade zinc, this anode is engineered to corrode preferentially, ensuring that your stainless steel and bronze fittings remain intact. It fits directly into sea strainer housings where raw saltwater flows, providing continuous cathodic protection without restricting water flow or adding bulk to engine compartments.

Ideal for owners of inboard and outboard engines with raw-water cooling systems, the Tecnoseal SZ-1 is particularly beneficial for those operating in coastal or brackish waters where the risk of corrosion is heightened. Regular replacement is recommended every 1–2 seasons to maintain optimal protection.
