Reduced double screw M-M from 2" to 1"1/2 in anti-corrosion brass – CR – code: 7245I*H – Maestrini

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

La reduced double screw M-M Maestrini is a threaded fitting designed to create a direct connection between two components with female threading, when the sizes do not match. In a single solution, it allows transitioning from 2″ a 1″1/2, maintaining a neat and easily inspectable installation.

Fitting type and threaded configuration

The reduced double-ended screw is a joining element with male threading on both sides (configuration M-M). It is designed to connect two female parts without resorting to combinations of multiple fittings, when an integrated size reduction is needed.

• Type: reduced double screw
• Connection: M-M (male-male)
• Reduction: 2″ → 1″1/2

The reduced geometry helps manage the diameter transition cleanly: a single component, a single adaptation point, an immediate reading of the configuration during installation and maintenance.

Material: corrosion-resistant brass

The fitting is made of anticorrosion brass, a common choice in hydraulic and plumbing fields when a material suitable for technical uses and contexts where resistance to external agents is a practical requirement is desired. The indication CR is reported in the product designation and allows consistent recognition of the variant according to the manufacturer's coding.

• Material: anticorrosion brass
• Indication/series: CR

Item identification and warehouse management

For purchases, reorders, and spare parts management, correct identification is essential, especially when working on existing systems or bill of materials. This item is a Maestrini with supplier code 7245I*H.

• Brand: Maestrini
• Supplier product code: 7245I*H

Where it is most often used

• Adaptation between fittings or accessories with female threads of different sizes.
• Maintenance and restoration of existing lines, when a replacement component requires a size transition.
• Integration of accessories on already installed systems, maintaining a direct and orderly connection.
• in civil or light industrial fields, where brass fittings are commonly used. and nautical/on-board contexts, where clarity of connection and recognizability of the replacement part are important operational aspects.

Why the M-M configuration is useful

The configuration male-male is particularly convenient when both components to be joined have a female inlet. In these cases, the reduced double screw allows a linear connection, reducing intermediate steps and simplifying checks during inspections.

Operational advantages

Size reduction in a single fitting

Switching from 2″ a 1″1/2 with a single component helps keep the system more rational. In many installations, this approach is easier to manage compared to solutions composed of multiple elements in series, especially when a clear and immediately identifiable adaptation point is desired.

Material suitable for technical contexts

The’anticorrosion brass is often chosen for components intended for systems and maintenance, where fittings may be subject to challenging environmental conditions and where replaceability over time is a practical aspect. The choice of material, combined with clear product coding, supports professional management of the replacement.

Usage and installation notes

Before assembly, it is advisable to verify that the requested configuration is actually M-M and that the sizes correspond to the components to be connected: 2″ on one side and 1″1/2 on the other. During installation, a good practice is to work with clean and well-maintained threads, to facilitate screwing and reduce the risk of damage.

Practical notes for interventions on existing lines

• Alignment check: verify that the connected components are properly aligned to avoid mechanical stresses on the fitting.
• Dimensional compatibility check: confirm the sizes on the 2″ side and the 1″1/2 side before closing the system.
• Sealing and tightening procedures: adhere to system practices and the instructions of the appointed technician, depending on the line and operating conditions.

Product summary
