Product information

Description

Sacrificial anode with gasket by Biawar, dimensions 21.3 × 435 mm, designed to reduce corrosion in heating and hot-water systems. This replaceable magnesium anode rod provides cathodic protection for metal components inside boilers, water heaters and storage tanks. The integrated gasket simplifies installation and helps maintain a pressure-tight connection between the anode mounting point and the vessel, extending service life and decreasing maintenance related to rust and scale.

Advantages

The anode offers targeted protection against electrochemical corrosion by preferentially corroding instead of the protected metal surfaces. Its standardized diameter and length make it compatible with a wide range of domestic and commercial water heating appliances that accept a 21.3 mm anode. The built-in gasket ensures a reliable seal to prevent leaks and reduces the need for additional sealing materials. Because the anode is replaceable, it allows planned maintenance without major disassembly of the system.

Suitable for

  • Boilers and central heating systems that accept a 21.3 mm anode rod
  • Domestic and commercial water heaters and storage tanks
  • Replacement during routine maintenance to prevent corrosion and extend appliance life

Key specifications

  • Material: sacrificial anode (magnesium or compatible sacrificial metal)
  • Outer diameter: 21.3 mm
  • Length: 435 mm
  • Integrated sealing gasket for pressure-tight installation
  • Replaceable design for easy maintenance

How to use

Shut down and depressurize the appliance following the manufacturer’s safety instructions before beginning work. Locate the anode port or inspection opening on the boiler, water heater or tank, remove the old anode if present, and inspect the mounting threads and seating surface for damage or excessive corrosion. Install the new Biawar anode with gasket by threading it into the port until the gasket compresses to form a seal; tighten to the specified torque recommended by the appliance manufacturer. Re-pressurize the system and check for leaks. Periodically inspect the anode condition as part of routine maintenance and replace when the sacrificial metal is substantially consumed.

Usage recommendations

Use this anode in appliances that specify a 21.3 mm replaceable anode rod and a gasketed seal. For reliable protection, follow the water heater or boiler manufacturer’s service intervals and replace the anode when consumption indicates reduced protective effectiveness. If unsure about compatibility, consult appliance documentation or a qualified service technician before installation.
