Heavy-duty hose holder type “Rome” with 2"1/2×70 tapered thread in CR anti-corrosion brass – code: 7156L*70T – 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 practically connect a flexible hose to a threaded connection point. This version is made of CR anticorrosion brass and features a tapered thread, a typical solution in plant engineering applications where a reliable coupling between fitting and threaded seat is sought.

The product is identified by the Maestrini code 7156L*70T and it is suitable for technical contexts such as plant engineering, maintenance, and onboard installations, where the choice of components and materials is an integral part of the quality of the intervention. The “Roma” geometry and construction heavy make it suitable for applications where a robust and easy-to-handle fitting is preferred during assembly.

Features and construction details

Type and configuration

• Type: male hose connector (M) heavy type “Roma”.
• System side connection: tapered thread.
• Connection on tube side: hose holder for flexible hose.
• Indicated size: 2″1/2×70 (as per product denomination).
• Product code: 7156L*70T.
• Brand: Maestrini.

Material: CR anticorrosion brass

The fitting is made of CR anticorrosion brass, material commonly chosen in plant engineering for its suitability in environments where good resistance to aggressive conditions is useful. In nautical and onboard plant applications, material selection is a key aspect: anti-corrosion brass is often preferred when a reliable metal component suitable for technical installations is desired.

Tapered thread: what it means in practice

The tapered thread is a connection solution where the coupling occurs progressively during screwing. During installation, this can facilitate the creation of a stable connection, especially when working on existing systems or components with compatible tapered threads. For correct installation, it is important to always check the compatibility of the counterpart’s thread and adopt the sealing procedures provided by your assembly standard.

Typical applications

The heavy male hose fitting type “Roma” is used in numerous scenarios of hydraulics and fittings, including nautical contexts and onboard plant engineering. In general, it is indicated when you need to:

• connect a flexible hose to a point with tapered thread;
• make branches or connections on technical lines where the use of brass fittings is expected;
• interventions of maintenance or replace existing fittings with an equivalent component in type and size;
• installations where a fitting robust and professional setup is preferred.

Since compatibility depends on the type of pipe, the counterpart’s thread, and the system conditions, it is advisable to always check your system’s specifications before purchase and assembly.

Advantages for installation and maintenance

Practical connection between flexible hose and threaded fitting

The hose fitting is a direct solution to transition from a flexible line to a threaded connection. This approach simplifies many plant configurations, especially when working with piping that requires insertion on a hose fitting and tightening with a clamp or equivalent system (depending on the pipe and installation practice).

Material suitable for technical contexts

The’CR anticorrosion brass is a recurring choice in professional environments. In particular, in environments where corrosion is a factor to consider, selecting a suitable material contributes to the proper management of the system over time, reducing the need for unplanned interventions.

“Heavy” format for a solid feel

The construction heavy is often preferred when a fitting with greater consistency and perceived robustness is desired, useful during assembly and disassembly operations. This can be an advantage in maintenance, where repeatability of operations and component resistance are practical aspects.

Usage and installation notes

Checks before installation

• Thread check: make sure the counterpart has a conical compatible thread.
• Dimension check: check that the size 2″1/2×70 matches the system’s requirements and the pipe to be connected.
• Surface condition: check that the mating surfaces are clean and free of damage that could compromise assembly.

General guidelines for pipe connection

Insert the hose onto the hose connector correctly and use a clamping system suitable for the type of hose used (for example, a clamp or an equivalent solution provided by the installation). The choice of clamping depends on the hose material and the operating conditions of the system; always follow good practices and the hose manufacturer's instructions.

Seal on tapered thread

For sealing on tapered thread, adopt the procedure normally used in your field (based on standards and system materials). In case of doubt, it is advisable to refer to the installer technician's instructions or company practices, avoiding solutions incompatible with the materials involved.

Identification and reorder

To facilitate spare parts management and reordering, refer to:

• Code: 7156L*70T
• SKU: MAES00000299
• Brand: Maestrini

These references help reduce errors during procurement, especially when managing multiple variants of fittings and similar sizes.
