3/4" 45° F.F. elbow in anticorrosive CR brass - code: 7120E - Maestrini

45° F.F. Elbow 3/4″ in CR anti-corrosion brass – Maestrini (code 7120E)

The 45° F.F. elbow 3/4″ in CR anti-corrosion brass Maestrini, code 7120E, is a fitting designed to make 45° deviations in systems where a connection female/female and a construction in brass with treatment/finish indicated as CR anti-corrosion. It is a typical solution for the neat creation of lines and branches, useful when you want to avoid too tight curves or when space requires a controlled change of direction.

In technical and plant engineering fields (including maintenance and outfitting of onboard systems), a 45° fitting allows managing the piping route more linearly compared to a 90° angle, facilitating routing and component organization. This item is part of the Maestrini fittings range, a brand known in the sector for components intended for systems and technical accessories.

Product features and details

Type of fitting

• Shape: gomito 45°
• Connections: F.F. (female/female)
• Size: 3/4″

Material and finish

• Material: brass
• Anti-corrosion indication: CR (as per product description)

The choice of brass is common in fittings for systems due to its machinability and use in many technical applications. The term CR anti-corrosion identifies the proposed variant, useful when a component with attention to resistance in contexts where corrosion may be a factor is desired.

Identification and supply

• Manufacturer/Supplier: Maestrini S.R.L. Sole Proprietorship
• Supplier product code: 7120E
• SKU: MAES0000114

For orders, reorders, and spare parts management, it is advisable to refer to the code 7120E and the SKU indicated, so as to reduce the risk of errors during procurement.

Typical applications

This 45° F.F. elbow 3/4″ is suitable for applications requiring a 45° change of direction on a line with female connections. In general, it can be used in:

• in civil or light industrial fields, where brass fittings are commonly used. and maintenance of service lines
• Fittings and refitting where optimizing the piping route is necessary
• Onboard systems and nautical applications, when brass fittings and a 45° configuration are required
• Repair interventions or replacement of existing fittings with the same geometry and size

The 45° configuration is often chosen to accompany the piping route more gradually, maintaining a clean layout and reducing the need for complex adaptations in technical spaces.

Operational advantages

Orderly management of the piping route

An elbow at 45° helps to build more linear and “smooth” paths compared to sharper direction changes. This can be useful when you want to:

• maintain a smoother routing of lines
• adapt to space constraints and technical passages
• create branches and connections with geometry consistent with the system

Female/female connection

The configuration F.F. is practical when the system requires an intermediate fitting between male elements or when working with components that provide for such coupling. During design or maintenance, having a clear understanding of the threading/connection type avoids incompatibilities and reduces intervention times.

Brass with CR anti-corrosion indication

The presence of the wording CR anticorrosion brass makes this item a consistent choice for contexts where a brass fitting with attention to corrosion protection is desired, in line with what is stated in the product name.

Usage and important notes

Checks before installation

For a correct choice of fitting, it is good practice to verify:

• Size: that the line is actually 3/4″
• Connection type: that a F.F. (female/female)
• Geometry: that the required angle is 45° and not different
• Code: matching with 7120E in case of replacement or spare

Installation and maintenance

Installing fittings requires attention to the condition of the threads and the cleanliness of the mating surfaces. In maintenance contexts, it is advisable to work with appropriate tools and check the alignment of parts to avoid unwanted mechanical stresses on the system.

In case of replacement, always compare the removed fitting with the new one (size, F.F. type, 45° angle) and use components compatible with the rest of the line. If the application is in a specific context (nautical/onboard systems), also consider the installation environment and the maintenance practices provided by your system.

Note on compatibility and specifications

The information provided in this sheet describes type, size, material, angle, and code as per available data. For particular requirements (threading standards, use on specific fluids or operating conditions), it is advisable to check the manufacturer's technical documentation or the specifications of the system where the fitting will be installed.

FAQ – Frequently Asked Questions

What does F.F. mean in this Maestrini elbow?

F.F. indicates that the fitting has both ends with female connection (female/female), useful when the system requires this type of coupling.

What is the size of the fitting?

The indicated size for this elbow is 3/4″.

What material is the 7120E elbow made of?

The fitting is made of brass, with an indication of CR anticorrosion variant/finish as reported in the product name.

When is it convenient to use a 45° elbow instead of a 90° one?

A 45° elbow is often chosen when a more gradual change of direction is desired or when the piping route requires a less sharp deviation to maintain a neat layout.

What is the product code to identify this Maestrini item?

The supplier product code is 7120E. For internal management, the SKU MAES000000114 may also be useful.
