M-F Reduction from 1/4" to 1/8" – code: 0241B*A – Maestrini

M-F Reduction from 1/4" to 1/8" Maestrini (code 0241B*A)

The M-F reduction from 1/4" to 1/8" Maestrini brass threaded rod – code 0210D code 0241B*A, is a fitting designed to adapt two threads of different sizes within a system. It is a practical solution when connecting a component with a 1/8" fitting to a line or accessory prepared for 1/4", or when standardizing connections during maintenance or system modification.

In technical fields (including nautical and onboard systems), this type of reduction is often used to simplify the integration of instruments, valves, accessories, and branches, maintaining a neat and consistent connection with the already installed components. The format Male–Female (M-F) allows a direct insertion between two elements, reducing the need for additional adapters.

Features and construction details

The fitting is a M-F reducer with passage from 1/4" to 1/8". It is suitable for applications where a thread adaptation is required without altering the existing system configuration.

• Supplier code: 0241B*A
• Brand / supplier: Maestrini S.R.L. Sole Proprietorship
• Material: brass

M-F Configuration (Male–Female)

The configuration M-F allows connecting a female-threaded element to a male-threaded element, introducing the size reduction between the two. This approach is useful when:

• you need to adapt a component with a smaller fitting to a larger provision (or vice versa, depending on the system configuration);
• you want avoiding chains of adapters and maintaining a more linear connection;
• intervening in maintenance replacing an accessory with one of a different fitting.

of 1/2″

The reducer is indicated as made of brass. This material is commonly used in fittings for systems due to its widespread use in hydraulics and good workability, making it suitable for many technical applications where threaded fittings are used.

Typical applications

The Maestrini 0241B*A reducer is used in various contexts of hydraulics and fittings, including onboard technical systems, when it is necessary to switch from one thread size to another in a simple and orderly way.

In system installation and maintenance

• Accessory adaptation with different fittings (from 1/4" to 1/8").
• Retrofit interventions on existing lines, when a replacement component has a different thread.
• Creating branches or secondary connections where the available components are sized 1/8".

In the nautical field (general setting)

Onboard systems, the reducer can be useful to integrate components and instruments in technical spaces where different standards and sizes often coexist. It is a practical choice when you want to maintain a clean and easily inspectable configuration, especially in areas where accessibility is limited.

Operational advantages

Although it is a simple component, a correct reducer can make a difference in the quality of assembly and ease of system management over time. This Maestrini M-F reducer is designed for those seeking a direct adaptation between two thread sizes, with a component identifiable and consistent with technical fittings.

Why choose a dedicated reducer

• Neater integration: allows transitioning from 1/4" to 1/8" without improvised solutions.
• Simplified maintenance: a proper fitting reduces complications during disassembly and component replacement.
• Clearer spare parts management: the code 0241B*A helps quickly identify the product when reordering.
• Versatility of use: useful in many threaded system configurations where different sizes are present.

Usage and installation notes

To achieve a correct assembly, it is important to always check the thread compatibility and the correct sequence of connection between male and female. In particular, before installation:

• check that the required sizes are actually 1/4″ and 1/8″ at connection points;
• check the configuration of the elements to be connected (which side is male and which is female) to avoid incorrect pairings;
• ensure that surfaces and threads are clean and free of residues that could compromise the connection.

Good practices (general indications)

During assembly, follow the usual procedures provided for threaded fittings in your system. If the application requires it, use a sealing system suitable for the thread and the fluid handled, following the instructions of the sealing material manufacturer and workshop practices. In case of doubts about compatibility, operating conditions, or particular configurations, it is advisable to consult a technician.

FAQ – Frequently Asked Questions

What does M-F reduction from 1/4" to 1/8" mean?

It indicates a reduction fitting with one male side and one female side (M-F) that allows connecting two components with different thread sizes, going from 1/4" to 1/8".

What is the Maestrini product code?

The supplier product code is 0241B*A.

What material is the reduction made of?

From the existing product description, it is made of brass.

When is a reduction from 1/4" to 1/8" used?

It is used when a component or accessory has a 1/8" fitting but the system (or provision) is 1/4", or during maintenance and system modifications to adapt different threads.

How do I check if it is the right reduction for my system?

Check that the connection points actually require the sizes 1/4" and 1/8" and that the male/female configuration matches the components to be connected. In case of doubt, a technical consultation before assembly is advisable.
