Heavy-duty M hose fitting type “Roma” conical thread in anti-corrosion brass 3"x75 – code: 7156M*75T – Maestrini

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

The Heavy male hose fitting type “Roma” Maestrini is a fitting designed to practically connect a flexible hose to a line with tapered threading. The construction in anticorrosion brass makes it a suitable choice for technical contexts where reliable materials and good durability over time are required, such as plant engineering, maintenance, and typical onboard applications.

This version is identified by the Maestrini code 7156M*75T and is indicated as 3″x75, according to the product's commercial name. The “heavy” construction and “Roma” geometry recall a type widely used in the hydraulic field for tube/fitting connections, with a design oriented towards robustness and ease of integration into existing systems.

Features and construction details

Type of fitting

• Male hose connector (M): configuration with hose connector end for flexible hose and male threaded side.
• Type “Rome”: commonly used shape and reference standard in hose fittings for plant engineering.
• Heavy-duty execution: indication of a construction oriented towards solidity and use in technical contexts.

Threading and connection

• Tapered thread: typical solution for connections requiring a stable coupling on compatible components.
• Tube/fitting interface: hose side designed for the insertion of flexible pipes, with fastening through suitable systems (e.g., clamps or equivalent tightening), depending on the plant.

Material

• Anti-corrosion brass: material chosen for applications where corrosion resistance is an important requirement, even in demanding environments.

Product identification

• Brand: Maestrini
• Supplier code: 7156M*75T
• Name: 3″x75 (as per product description)

Typical applications

This hose fitting is suitable for uses where it is necessary to make a connection between a tapered threaded line and a flexible tube.

Usage contexts

• Hydraulic systems and service lines with flexible pipes.
• Maintenance and replacement of worn or no longer suitable fittings.
• Technical setups where a brass fitting with anti-corrosion characteristics is preferred.

Advantages

Material choice

The’anticorrosion brass is often preferred in plant engineering for its suitability to work in environments where exposure to moisture and external agents can be significant. This helps maintain the fitting's functionality over time, respecting the conditions of use and correct installation.

Hose tail size

The configuration hose holder allows a direct connection with flexible tubes, making it practical when handling non-rigid sections or when the plant requires some adaptability in the tube path.

Tapered thread

The tapered thread is a common solution for technical connections: if paired with compatible components and properly installed, it allows a stable coupling suitable for many plant configurations.

“Heavy” version”

The version heavy is designed for those seeking a fitting with a robust setup, typically chosen in professional settings and applications where components must be suitable for continuous use and variable operating conditions.

Usage and installation notes

To achieve correct assembly it is important to check the compatibility between the tapered thread of the fitting and the counterpart of the plant, in addition to the correct choice of the flexible tube to be inserted on the hose side. During installation, also pay attention to the tube tightening system (for example, with a suitable clamp), selecting it based on the type of tube and application.

Good practices

• Dimensional check: verify that the indicated size (3″x75) is consistent with the system requirements and with the components already present.
• Thread verification: ensure that the counterpart is suitable for a tapered thread and that the coupling occurs without abnormal forcing.
• Tube insertion: insert the tube onto the hose side completely and evenly, avoiding folds or tensions that could compromise the connection.
• Adequate tighteninguse a fastening system appropriate for the pipe and intended use, periodically checking the seal according to operating conditions.

Important note

The sealing methods and assembly procedures depend on the type of system and the connected materials. In case of doubt, refer to industry installation practices or the appointed technician, especially in onboard applications or systems where connection reliability is an essential requirement.

Summary

• Fitting male hose fitting “Roma” type in anticorrosion brass
• Tapered thread
• Maestrini – code 7156M*75T
• Name: 3″x75
