Zinc Anode with Brass Mounting Plug

The Tecnoseal 01451 combines a zinc sacrificial element with a brass mounting plug. The zinc rod provides the sacrificial material for galvanic corrosion protection, while the brass plug serves as the mechanical connection to the water heater.

The plug features a 1/2" GAS conical (BSPT) external thread and a 22 mm head dimension. This tapered threaded connection must match the corresponding fitting on the boiler or water heater.

Application and Compatibility

This pencil anode is intended for compatible Isotherm marine boilers and water heaters using a 17 mm diameter zinc rod and a 1/2" BSPT brass mounting connection.

Before replacement, compare the original anode's rod diameter, length, plug dimensions and thread specification. BSPT tapered threads should not be confused with BSPP parallel or NPT threaded connections.

Replacement and Maintenance

The zinc rod gradually sacrifices its material while helping protect the associated metallic components against galvanic corrosion. Periodic inspection allows the anode to be replaced when sufficiently consumed.

When replacing the anode, verify the condition of the existing mounting connection and confirm that the replacement matches the original dimensions.

Supply: One Tecnoseal 01451 zinc sacrificial pencil anode complete with brass mounting plug.
