Hull and transom anode 70mm – code: L8120007 – Trem

Anode for hulls and transom plates Trem (code L8120007)

The’anode for hulls and transoms Trem, code L8120007, is a component dedicated to the cathodic protection of metal parts installed in a marine environment. It is made of zinc (ZN) and is designed for use on hulls and transoms, where the presence of water and the coexistence of different metals can promote galvanic corrosion phenomena.

Product features and details

Material

The anode is made of ZN (zinc), material commonly used for cathodic protection in nautical applications. The anode works by “consuming” over time to help protect metal parts electrically connected to the system or structure on which it is mounted.

Dimensions and identifiers (variant L8120007)

• Product code: L8120007
• Declared application: hulls and transom plates
• Material: ZN
• A Ø: 70 mm
• B: 17 mm
• C Ø: 8 mm
• Polipodio Art. Reference: NC024
• Package: 1 / PCS

Typical applications

This anode is designed for use on hulls and transoms. In practice, it can be used where it is necessary to add or restore a cathodic protection point on surfaces and components exposed to water.

When it can be useful

• Replacement of an anode consumed during periodic maintenance.
• Restoration of the protection after interventions on the hull or transom (e.g., storage or maintenance work).
• Alignment to an already existing configuration on board, maintaining dimensions and drilling compatible with the existing installation.

Operational advantages

A correctly sized and installed anode helps manage the maintenance of exposed metal parts more orderly. Without making unverifiable promises or claims, the most common practical advantages are:

• Support for cathodic protection of hull and transom, under typical marine environment conditions.
• Identifiable spare part via Trem code L8120007 and reference NC024, useful for reordering and spare parts management.
• Dedicated format (Ø 70 mm) for those who need to respect existing space and holes.
• Simple handling from the warehouse: package 1 / PCS.

Usage and installation notes

To ensure proper functioning of cathodic protection, the anode must be installed carefully. Below are some general guidelines (to be adapted to your system and onboard instructions):

Pre-assembly checks

• Dimensional check: check A Ø 70 mm, B 17 mm and C Ø 8 mm compared to the part to be replaced and the fixing points.
• Identification: confirm the code L8120007 (and, if needed, the reference NC024).
• Surface condition: make sure the contact and fixing area is suitable and free of obstacles that could compromise electrical contact.

During installation

• Correct fastening: use the provided drilling (C Ø 8 mm) and ensure the anode is well tightened, without abnormal forcing.
• Electrical contact: the effectiveness of cathodic protection also depends on contact; avoid conditions that could isolate it (e.g., layers that interrupt continuity).
• Positioning: install the anode at the point provided by the system or the existing configuration on hull/transom.

Maintenance and replacement

• Periodic inspection: check the anode's consumption status during normal onboard inspections or storage.
• Replacement: when the anode is significantly consumed, plan replacement with an equivalent spare in size and material.
• Material consistency: this version is in ZN; in case of doubts about the choice of the most suitable material for your configuration, consider consulting a technician.

Practical advice

If you are purchasing for replacement, always compare the code on your spare part and the main dimensions. In case of uncertainty between series variants, it is preferable to choose based on dimensions and holes already present on the installation.
