Reduced double screw M-M from 1" to 1"1/4 in anti-corrosion brass – CR – code: 7245G*F – Maestrini

Reduced double screw M-M in anti-corrosion brass (CR) Maestrini

La reduced double screw M-M Maestrini is a threaded fitting designed to connect two components with male-male threading and with different sizes, facilitating adaptation between lines or accessories already present in the system. This version is made of anticorrosion brass (indication CR) and is suitable for contexts requiring materials appropriate for maintenance and installation of technical systems, including nautical and onboard systems.

The product is identified by the Maestrini code 7245G*F and is a practical solution when you need to switch from a thread from 1" to a 1"1/4, maintaining a linear and neat connection.

Product features and details

Type and function

• Type: reduced double screw
• Connection: M-M (male-male)
• Reduction: from 1" a 1"1/4
• Use: adaptation between components with different threads, connection between fittings/valves/accessories with threaded attachment

Material

• Material: anticorrosion brass
• Indication: CR

Anti-corrosion brass is commonly chosen in system engineering for its suitability in applications where resistance to external agents and long-term stability are important. From a conservation perspective, it is always recommended to verify material compatibility with the fluid and the specific installation environment.

Product identification

• Brand: Maestrini
• Supplier product code: 7245G*F
• SKU: MAES000000152

Typical applications

This reduced double screw M-M it is suitable for many situations where a threaded connection with size reduction is needed, for example:

• Hydraulic systems and technical lines where components with different threads are integrated.
• Onboard systems (nautical) for adaptations and restorations during maintenance interventions, when accessories or sections with non-uniform sizes need to be connected.
• Retrofit interventions or component replacement: useful when the new element has a different connection compared to the existing line.
• Connections between fittings and threaded accessories in technical spaces, where a simple and direct solution is preferable.

The choice of a reduced double screw allows maintaining a compact and functional connection, avoiding improvised adaptations and improving the installation order.

Usage and installation notes

Thread verification

Before installation, check that the threads of the components to be connected are consistent with the male-male configuration 1" e 1"1/4. and with the sizes.

. In case of doubts about the type of thread required by the system, a preventive check is advisable to avoid incompatibilities.

Assembly and sealing.

Maintenance

For threaded connections, it is important to adopt a correct assembly procedure and use sealing systems suitable for the application (based on system practices and the materials involved). Avoid excessive tightening and ensure that surfaces are clean and free of residues that could compromise the coupling.

FAQ – Frequently Asked Questions

What is a reduced double screw M-M?

It is a threaded fitting with two male ends (M-M) that allows connecting two components with female inlets, reducing or adapting the size between the two sides.
