Heavy-duty hose holder type “Roma” with 1"1/4×40 tapered thread in CR anti-corrosion brass – code: 7156G*40T – Maestrini

Heavy male hose connector type “Roma” Maestrini in CR anti-corrosion brass

The Heavy male hose fitting type “Roma” Maestrini is a fitting designed to create practical connections between a line with male tapered thread and a flexible hose. The construction in CR anticorrosion brass makes it a typical choice for applications in plant engineering and maintenance, where a reliable component suitable for technical contexts is sought, including those related to boating and onboard systems.

This version is identified by the Maestrini code 7156G*40T and is characterized by 1"1/4 tapered thread and hose connector attachment 40. The “Roma” geometry and “heavy” configuration are aimed at professional use, focusing on the robustness of the fitting and the stability of the connection with the tube.

Typical applications

A hose connector with tapered thread is commonly used when it is necessary to connect a flexible tube to a threaded component of the system (for example a branch, a valve body or an intermediate fitting), maintaining a neat and easily inspectable installation. In nautical and plant engineering fields, this type of fitting is often chosen for interventions of:

• maintenance and replacement of connections on lines with flexible tube;
• construction or modification of plant sections with transition from threaded to tube;
• installations where a component in anticorrosion brass for contexts exposed to demanding conditions.

The hose connector profile is designed to facilitate the insertion of the tube and the seal using a clamp or equivalent systems (not included), according to the installation practices adopted on the system.

Operational advantages

Practical solution for thread-to-tube transition

The combination male tapered thread + hose holder allows easy management of the connection between rigid threaded components and flexible pipes, reducing the need for multiple adapters when the system configuration allows it.

CR anti-corrosion brass for technical contexts

The use of CR anticorrosion brass is suitable for applications where a material traditionally used in fittings and system components is preferred, even in environments where corrosion resistance is an important requirement. In the nautical field, the choice of material is often a key element in the selection of fittings.

“Heavy” version and “Rome” model”

The wording heavy and the type “Roma” identify a family of fittings aimed at professional use. This helps maintain component consistency within the system and simplifies spare parts management, especially when working on existing installations that use the same series.

Usage and installation notes

Checks before purchase

code match

• the thread size plant side (in this case 1"1/4) and compatibility with the counterpart;
• the tube size to be connected (hose connector 40) and suitability of the clamp or tightening system used;
• the available space for tube insertion and possible tightening.

Assembly on the tapered thread side

The tapered thread is commonly used for connections where the seal relies on the thread coupling and, if provided by the installation procedure, suitable sealing materials. In the absence of specific system instructions, follow good assembly practices and the prescriptions of the connected component manufacturer.

Tube connection on the hose connector

For the tube side, insert the flexible tube onto the hose connector up to the stop (when possible) and tighten with an appropriate system (e.g., clamp), selected based on the type of tube and application. It is good practice to check the tube alignment to avoid bends and stresses that could strain the fitting over time.

Spare parts and quick identification

For reorders or replacements, refer to the code 7156G*40T and the full description: heavy-duty M hose holder type “Roma” with 1"1/4×40 tapered thread in CR anticorrosion brass. This reduces the risk of errors during procurement, especially on systems where similar sizes coexist.

Note

The product is supplied as a single fitting. Any installation accessories (tube, clamps, sealants, or other components) are not included unless otherwise indicated.

FAQ – Frequently Asked Questions

What is a male hose connector with tapered thread?

It is a fitting that on one side has a male tapered thread to connect to a threaded component of the system and on the other a hose connector to insert a flexible tube and secure it with an appropriate clamping system.

What are the measurements of this Maestrini model?

The version on the card is indicated as 1"1/4×40: 1"1/4 tapered thread on the plant side and 40 hose holder on the tube side.

What material is the fitting made of?

It is made of CR anti-corrosion brass, as indicated in the product name.

What is the product code to correctly identify this hose connector?

The Maestrini supplier product code is 7156G*40T. For e-commerce, the associated SKU is MAES000000342.

Is it suitable for marine systems?

It is a fitting typically used in technical and maintenance contexts; the presence of CR anti-corrosion brass makes it a common choice also in the nautical field. It is still advisable to check compatibility with your system and the type of tube used.
