Articulated Magnesium Tank Anode S/S Core 450mm (3X 150mm)

The STA450A Articulated Anode Rod (Φ22 × 450 mm) is a sacrificial protector designed to extend the life of your water heater tank. By attracting corrosive elements in the water through an electrochemical process, the rod corrodes instead of the tank — preventing rust, leaks, and costly replacements. Made with a 304 stainless steel ¾-inch plug and internal stainless steel filling, this rod offers strength, durability, and easy installation in a wide range of water heating systems.

How It Works

• Electrochemical Process: The steel water heater tank is less active than the anode rod. The rod (made from active metals) corrodes first, protecting the tank.

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

• Sacrificial Corrosion: The rod oxidizes and deteriorates over time, distributing electrons and preventing tank corrosion.

• Tank Protection: This process extends the service life of your water heater.

When to Replace It

• Inspection Interval: Check every 1–3 years.

• Replacement Trigger: Replace when over 50% consumed.

• Signs of Wear: Rotten egg smell (sulfur/hydrogen sulfide) or discolored water indicates the rod is no longer effective.

• Sacrificial protection — corrodes in place of your water heater tank, significantly extending its lifespan.
• Dimensions: Φ22 × 450 mm — compact, articulated design for easy installation.
• ¾-inch 304 stainless steel plug — durable, corrosion-resistant connection.
• Electrochemical protection — attracts corrosive ions, preventing tank rust and leaks.
• Internal stainless steel filling for improved performance and structural strength.
• Ideal for residential and commercial hot water cylinders.
