Heavy-duty M hose holder type “Roma” conical thread in anti-corrosion brass 3"x80 – code: 7156M*80T – Maestrini

Heavy-duty M hose holder type “Roma” Maestrini with conical brass anti-corrosion thread

The Heavy male hose fitting type “Roma” Maestrini is a fitting designed to make connections between a line with tapered thread and a flexible hose, in contexts where robust components suitable for technical applications are required. The construction in anticorrosion brass makes it a typical choice for installation and maintenance, even in environments where exposure to moisture and external agents is a factor to consider.

This version is identified by the Maestrini code 7156M*80T and is described as 3″x80. For a correct selection, it is always advisable to verify the correspondence of the measurements with the pipe and the threading of the system being worked on.

Features and construction details

The fitting belongs to the family of “heavy M” hose holders type “Roma,” a designation that refers to a construction oriented towards solidity and ease of installation in a professional context. The hose holder element allows the insertion of the flexible hose, while the threaded side enables connection to components with compatible threading.

Material: corrosion-resistant brass

The body in anticorrosion brass It is commonly used in fittings for hydraulic and technical systems, thanks to its suitability to operate under variable conditions. In nautical applications and onboard systems, the choice of material is often decisive to maintain the reliability of the connection over time, especially in the presence of moisture or aggressive atmospheres.

Tapered thread

The fitting is equipped with tapered thread, a solution used for threaded connections where the conical geometry contributes to the sealing of the connection based on correct installation and matching with the counterpart. The compatibility of the thread and the adoption of any sealing systems (if provided by the system procedure) must be evaluated according to the specific application.

Type: hose holder

The hose holder side is designed for the insertion of a flexible hose. In maintenance and system contexts, this configuration is useful when flexible lines need to be connected to rigid components or threaded connection points, maintaining an orderly and inspectable installation.

Product identification

• Brand / supplier: Maestrini
• Supplier product code: 7156M*80T
• Description of the measurement reported: 3″x80

Note: the dimensional notation is reported as per product identification. To avoid errors during ordering or replacement, always compare the actual measurements required by the system (pipe, hose holder, and threading).

Typical applications (nautical and plant engineering)

This hose holder is suitable for many situations where it is necessary to connect a flexible hose to a threaded connection, practically and with professional quality components.

Systems with flexible hoses

• Connections between flexible lines and components with conical threaded fittings.
• Creation or restoration of sections where the use of pipe is preferable for laying, vibrations, or accessibility reasons.
• Interventions on technical systems where replacing the fitting is necessary to restore an existing connection.

Maintenance and spare parts

In maintenance, the availability of a fitting clearly identified (code and type) helps to replicate the original system configuration, reducing uncertainties during replacement. The code 7156M*80T allows unambiguous reference to the component.

Operational advantages

Robust solution for technical contexts

The version “Heavy M” It is designed for use where fittings with solid construction suitable for professional processing and installation are preferred. It is a consistent choice when a reliable component suitable for technical systems is desired.

Material suitable for exposed environments

The’anticorrosion brass It is a material commonly selected for fittings intended for contexts where exposure to moisture and external agents is a factor to consider. This makes the fitting interesting for nautical applications and for systems installed in technical compartments or areas subject to condensation.

Simple integration in lines with tapered thread

The tapered thread Allows insertion into systems that adopt this type of connection. Correct compatibility with the counterpart and proper installation remain fundamental aspects to achieve a connection suitable for the system's needs.

Usage and installation notes

For a correct and lasting result, the selection and installation of a hose connector require some preliminary checks. Below are general guidelines, useful as an operational reminder.

Check measurements and compatibility

• Thread check: Check that the counterpart is compatible with a tapered thread.
• Tube inspection: Check compatibility between the internal diameter of the tube and the hose connector, based on the system configuration.
• Comparison with the replacement: In case of replacement, compare the existing fitting with the description and code 7156M*80T.

Mounting the tube on the hose connector

In general, the tube must be correctly inserted onto the hose connector and fixed according to the procedures provided by the system (for example, using tightening systems suitable for the type of tube and application). It is good practice to ensure that the tube is in good condition and that the connection is complete, avoiding abnormal tensions or bends.

Good maintenance practices

• Periodically inspect connections, especially in areas difficult to ventilate or subject to moisture.
• In case of disassembly, clean the surfaces and check the condition of the threading before reassembly.
• Use components consistent in material and type with the existing system, avoiding unverified combinations.
