Cap + zinc – code: 11886 – code: 913777 – Mase

Cap + zinc Mase (code 11886 / 913777) for heat exchanger

The Cap + zinc Mase is a spare part intended for the cooling circuit heat exchanger. It is a complete component that integrates a threaded cap and a sacrificial zinc anode, designed for the routine maintenance of Mase generator sets and the related heat exchangers indicated as compatible.

This item is identified by the codes 11886 (component code) and 913777 (Mase code) and is listed in the commercial documentation of the original Mase spare part.

Spare part features and details

Product identification

• Mase Code: 913777
• Component code: 11886
• Description: Cap + zinc heat exchanger C.S. 63763-63801
• Description (EN): Cap + Zinc – Heat Exchanger 63763-63801
• Supplier: Mase Generators S.p.A
• Type of spare part: full plug with sacrificial zinc anode

Composition and function

The spare part consists of:

• Threaded plug for the heat exchanger;
• Sacrificial zinc anode integrated.

The sacrificial zinc anode is a wear element: its presence helps protect the metallic components of the circuit, particularly in the exchanger, where galvanic corrosion phenomena may occur. For this reason, it is good practice to provide for periodic checks and the replacement when necessary, as part of generator set maintenance.

Application

The cap with anode is intended for use on cooling circuit heat exchanger, as a dedicated spare part for the configurations listed in compatibility.

Applications and compatibility

Compatible exchangers

The spare part is intended for heat exchangers:

• 63763
• 63801

Mase generator sets indicated

The code 913777 is indicated as an original spare part for Mase generator sets:

• VS 6.5
• VS 8.5
• VS 10.5
• VS 12.5
• VS 12.8 Y

Advantages for maintenance and spare parts

• Complete replacement: plug and anode integrated into a single item, useful for scheduled maintenance interventions.
• Corrosion management: the zinc sacrificial anode is a component typically used to limit the effects of galvanic corrosion in the heat exchanger.
• Clear codes for identification: presence of double coding (11886 and 913777) to facilitate matching with documentation and spare parts list.
• Original Mase spare part: indicated as a Mase Generators spare part, for those who wish to maintain correspondence with the manufacturer's documentation.

Usage and operational notes

When to replace the plug with anode

In the nautical and onboard plant field, the heat exchanger anode is normally considered a consumable component. It is advisable to include it in the periodic checks of the cooling circuit and consider replacement when the anode is worn or no longer suitable for its task.

Checks before purchase

• Compare the Mase code 913777 and/or the component code 11886 with its own documentation.
• Check that the installed heat exchanger is 63763 or 63801.
• In case of doubts about the generator configuration, refer to the spare parts list or the data of the generator set.

FAQ – Frequently Asked Questions

What is the difference between code 11886 and code 913777?

11886 is indicated as the component code, while 913777 is the Mase code associated with the original spare part. Both help to correctly identify the item in documentation and spare parts lists.

Does this spare part also include the sacrificial anode?

Yes. It is a complete plug with integrated zinc sacrificial anode.

For which heat exchangers is it indicated?

It is indicated for heat exchangers 63763 and 63801, as stated in the spare part description.

For which Mase generator sets is code 913777 indicated?

It is indicated for VS 6.5, VS 8.5, VS 10.5, VS 12.5, VS 12.8 Y, VS 15.5, and VS 17.5 Low, compatible with the use of heat exchangers 63763 or 63801.

How often should the zinc anode be replaced?

No unique periodicity is indicated in the available data. The anode is a wear component: it is usually checked during maintenance and replaced when worn or no longer suitable.
