Plug 1/4 ch. 17 + ZN anode D. 11 L 72 – 12492 – code: 913778 – Mase

Original Mase spare part: plug with integrated sacrificial anode

The 1/4" Plug CH.17 + ZN Anode Ø 11 L 72 is a Mase spare part designed for applications on systems with heat exchanger where a threaded plug integrating a sacrificial zinc anode. This component combines in a single piece the function of closing the inspection/service point and that of galvanic protection of the metal parts of the circuit.

The product is identified by the Mase code 913778 and by the component code 12492. It is a typical maintenance solution for onboard systems and generator sets, where periodic anode inspection is part of routine activities.

Spare part composition

The spare part consists of:

• 1/4" threaded plug;
• sacrificial zinc anode Ø 11 × 72 mm.

Applications (nautical and onboard systems)

The code 913778 is used on Mase Generators gensets equipped with heat exchanger which includes this type of plug/anode. In nautical and plant engineering contexts, the anode is a wear component and is normally checked during scheduled maintenance interventions.

Compatibility note: the precise compatibility depends on the model and by the serial number of the generator. In case of doubt, it is advisable to check the spare part code required by the exploded view or compare the markings/dimensions of the removed component.

Operational advantages (without forcing maintenance)

This plug with integrated anode is a practical solution because it combines two typical functions of the heat exchanger circuit into a single spare part: closure and galvanic protection.

• Original Mase spare part: useful to maintain consistency with the manufacturer's spare parts list.
• Immediate identification: codes 913778 and 12492 and clear dimensional description.
• Simplified maintenance: the anode is integrated into the plug and can be replaced as an assembly, according to the procedures provided by the system.
• Heat exchanger protection: the zinc anode is intended to work as a sacrificial element to protect the metallic components of the cooling circuit.

Use and maintenance notes

The sacrificial zinc anode functions to help protect against galvanic corrosion in the heat exchanger and in the connected metal parts. Being a consumable component, it is normally checked and, when necessary, replaced during the maintenance of the generator set.

Practical indications (generic)

• Verify that the 1/4" threading and the wrench CH.17 match the installed component.
• Compare Ø 11 and L 72 of the anode with the removed one, especially if the system has undergone modifications or replacements over time.
• For the certain choice of the spare part, refer to the Mase code 913778 (or to the component code 12492) and to the generator documentation.

Order advice

If you are purchasing for scheduled maintenance, it is useful to have on hand model and serial number of the generator set: these are the data that allow you to confirm compatibility precisely when there are exchanger variants or different configurations.

FAQ – Frequently Asked Questions

What is the Mase code for this spare part?

The spare part is identified by the Mase code 913778. The component code 12492 is also reported.

What does the component include?

It is a 1/4" threaded plug supplied complete with integrated zinc sacrificial anode.

What are the dimensions indicated in the official description?

The description states: 1/4" threading, CH.17 key, zinc anode Ø 11 and L 72.

What is the zinc anode used for?

The anode is intended to contribute to the protection of the heat exchanger and the metal parts of the circuit from galvanic corrosion. It is a wear component and is checked during maintenance.

How do I check compatibility with my Mase generator set?

Compatibility depends on the model and serial number of the generator and the configuration of the heat exchanger. For confirmation, check the spare part code in the Mase documentation or compare the installed component (threading and reported dimensions).
