Magnesium Tank Anode S/S Core 450mm

The STA450 Standard Anode Rod (Φ22 × 450 mm) is a sacrificial protector that shields your water heater tank from rust and corrosion. Installed directly into the cylinder, it attracts corrosive minerals and ions in the water, allowing the rod to corrode instead of the tank. Built with a 304 stainless steel ¾-inch plug and durable internal filling, this rod provides dependable, long-term protection to keep your water heater performing longer and more efficiently.

How It Works

• Electrochemical Process: The anode is a more active metal than the steel tank, so it corrodes first.

• Attracts Corrosive Elements: Minerals and ions in the water attack the anode rod, sparing the tank.

• Sacrificial Corrosion: The rod slowly degrades, distributing electrons that create a safer chemical balance.

• Protection: Extends the service life of the tank by preventing internal rust.

When to Replace It

• Check every 1–3 years during routine maintenance.

• Replace when over 50% consumed for continued protection.

• Warning signs: Rotten egg smell or discolored water, indicating the anode can no longer protect the tank.

• Sacrificial protection — corrodes in place of your water heater tank, preventing rust and leaks.

• Dimensions: Φ22 × 450 mm — standard design for a wide range of water heaters.

• ¾-inch 304 stainless steel plug for secure fitment and corrosion resistance.

• Electrochemical corrosion prevention — protects the steel tank by attracting corrosive elements.

• Durable stainless steel construction ensures reliable performance.

• Suitable for residential and commercial hot water systems.
