Reduced double screw M-M in anti-corrosion brass Maestrini (3/8″ → 1/4″)

The reduced double screw M-M Maestrini is a fitting component designed to connect two elements with male threading of different sizes, going from 3/8″ to 1/4″. is required. Made in anticorrosion brass, is suitable for use in plumbing and technical hardware where a compact, practical element is required and suitable for environments subject to humidity or demanding conditions.

Distinctive elements of the product

• Type: reduced double screw M-M (male-male).
• Threaded reduction: from , in the to 1/4″.
• Material: anticorrosion brass.
• Code: 7245C*B.
• Brand: Maestrini.

Anti-corrosion brass: because it is a practical choice

The’anticorrosion brass it is commonly used in fittings and technical small parts for its good ability to work in environments where humidity, condensation, or splashes may be present. In maintenance and plant engineering applications, the choice of material helps maintain the functionality of the connection over time, especially when the component is installed in locations not always easily accessible.

Typical applications

A reduced double screw M-M is used in many operational situations where adapt a threaded connection is necessary. It is a useful item both during installation and maintenance interventions, when replacing a component with a model with a different fitting or when integrating an additional accessory.

Where it can be used

• Hydraulic systems and service lines with threaded components.
• Maintenance and restoration of existing connections with non-uniform sizes.
• in civil or light industrial fields, where brass fittings are commonly used. in hardware and fittings.
• Nautical applications / onboard plant engineering, where the choice of materials suitable for humid environments is often preferable.

Operational advantages

This component is designed to offer a simple and neat solution when a reduction between two threaded sizes is needed. Although it is a small element, it can make a difference in the cleanliness of the installation and in managing plant modifications.

Why choose a Maestrini reduced double screw

• Immediate adaptation between 3/8″ and 1/4″ without resorting to combinations of multiple pieces.
• Compact solution and suitable for installations where space is limited.
• Anti-corrosion brass material, suitable for technical contexts subject to humidity.
• Clear identification by code 7245C*B, useful for reordering and spare parts management.
• Brand quality Maestrini, appreciated in components for systems and technical applications.

Usage and installation notes

For correct assembly, it is important to work on clean and well-maintained threads, avoiding forcing and misalignments that could compromise the coupling. In general, the reduced double screw is screwed between the two components to be connected, respecting the direction and size of each side.

Good practices

• Thread inspection: check that the 3/8″ and 1/4″ sizes correspond to the components to be connected and that there is no damage.
• Ordered assembly: screw by hand in the initial stages to avoid cross-threading, then complete tightening with suitable tools.
• Connection sealing: the choice of any sealing systems (if required by the application) should be evaluated based on the type of system and the coupled components.
• Maintenance: in case of frequent disassembly, periodically inspect the condition of the threads and the cleanliness of the surfaces.

Product identification

For technical requests, reorder or spare parts management, refer to:

• Maestrini Code: 7245C*B
• SKU: MAES000000144

If you are upgrading a system or replacing an existing component, this reduced double screw represents a practical solution to go from 3/8″ to 1/4″ while maintaining a male-male threaded brass anticorrosion connection.

FAQ – Frequently Asked Questions

What is a reduced double screw M-M?

It is a fitting with male threading on both sides (male-male) that allows connecting two threaded components, in this case with different sizes.

Which measurements does this Maestrini model connect?

This model creates a reduction from 3/8″ to 1/4″, maintaining an M-M connection.

What material is the reduced double screw 7245C*B made of?

It is made of anti-corrosion brass, a common choice for fitting and technical small parts components in humid or demanding environments.

What is the product code and how can I identify it for reordering?

The Maestrini code is 7245C*B. On the site, it is also associated with SKU MAES000000144, useful for internal management and reordering.

Is it suitable for onboard systems?

It can be used in technical and system contexts, including onboard systems, when a 3/8″ → 1/4″ threaded reduction is needed. It is still recommended to verify thread compatibility with the system components.
