Sacrificial Magnesium Anode NOVA TEC NT-S 250 mm with M6×10 mm Thread

Sacrificial magnesium anode NOVA TEC NT-S 250 mm with M6×10 mm threaded connection is a corrosion protection component designed for use in water heaters and hot water systems. The anode provides a preferential corrosion path, protecting steel tanks and internal metal parts by sacrificing its own material. Its compact 250 mm length and standard M6×10 mm thread make it compatible with many replacement and service situations where a replaceable anode is required.

Advantages

The magnesium composition offers effective protection against galvanic and electrolytic corrosion in potable water systems and domestic boilers. The 250 mm size balances capacity and ease of handling, while the threaded connection ensures straightforward replacement without specialized tools. The anode reduces the rate of corrosion on tank walls and internal components, which can extend the operational life of water heaters and lower maintenance requirements.

Suitable for

• Domestic and commercial water heaters with replaceable anodes
• Hot water storage tanks and cylinders
• Systems requiring a magnesium sacrificial anode for corrosion protection
• Maintenance and service replacements during routine boiler servicing

Key specifications

• Material: magnesium-based sacrificial anode
• Length: 250 mm
• Thread type: M6×10 mm threaded connection
• Primary function: cathodic protection of steel tanks and internal components

How to use

To install, shut off water supply and isolate the heater according to the manufacturer’s service instructions. Drain or partially drain the tank to access the anode port. Unscrew the old anode and remove any deposits or corrosion from the port area before inserting the replacement anode. Thread the new magnesium anode into the port and tighten to a firm fit without over-torquing. Refill the tank, restore water supply and, if applicable, return electrical or gas connections to service following safety checks and the appliance manual.

Usage recommendations

Inspect the anode periodically during scheduled maintenance and replace it when significant consumption or pitting is visible. For optimal protection, follow the water heater manufacturer’s guidance on inspection intervals and use compatible materials and thread sealants where specified. In hard water or aggressive conditions consider more frequent checks and consult technical documentation for complementary corrosion control measures.
