90° Elbow F.F. 1"1/4 in CR anticorrosion brass – code: 7090G – Maestrini

90° F.F. elbow in CR anti-corrosion brass Maestrini (code 7090G)

The 90° F.F. elbow. Maestrini is a fitting designed to make 90° direction changes in pipeline lines with filettatura femmina-femmina. The construction in CR anticorrosion brass makes it a suitable choice for technical contexts where a reliable component suitable for use in plant engineering is sought, including areas such as maintenance and installation of onboard systems.

This item is identified by the product code 7090G and is offered in the size 1"1/4, useful when sections of a system need to be integrated or modified while maintaining a threaded connection on both ends.

Features and construction details

An elbow fitting is an essential element when space or system layout requires a sharp change of direction. In this version, the F.F. configuration allows connecting two elements with male threading, simplifying the insertion of the elbow in already prepared sections or replacement interventions.

Main elements

• Type: 90° elbow
• Connections: thread female-female (F.F.)
• Size: 1"1/4
• Material: CR anticorrosion brass
• Code: 7090G
• Brand / supplier: Maestrini

Why CR anti-corrosion brass

The’CR anticorrosion brass is commonly chosen in plant engineering for its suitability in contexts where corrosion resistance is an important requirement. In nautical applications and technical environments, the selection of the fitting material contributes to system continuity and maintenance management over time.

F.F. configuration: when it is useful

The solution female-female is practical when:

• two components with male ends already present need to be joined;
• an existing line is being worked on and the same connection logic is to be maintained;
• a compact fitting is desired for a 90° turn without resorting to combinations of multiple pieces.

Typical applications

This elbow is suitable for use in hydraulic systems and generally in systems that use brass threaded fittings. In the nautical field, it can be used in onboard work and maintenance where lines with threaded fittings are present and an orderly and clean change of direction is necessary.

Examples of use (generic)

• making 90° turns in pipeline sections with threaded connections;
• adapting the path of a line in technical spaces or plant compartments;
• replacing an existing fitting with an equivalent component for restoration or maintenance.

Operational advantages

Choosing a 90° F.F. elbow in CR anti-corrosion brass offers practical benefits especially during installation and maintenance, where ease of assembly, connection consistency, and component quality matter.

• Simple integration: the F.F. threading facilitates connection with common male elements in plant engineering.
• Neat solution: allows a sharp change of direction without resorting to multiple fittings in series.
• Material suitable for technical contexts: CR anti-corrosion brass is a typical choice when resistance is sought in demanding environments.
• Clear identification: code 7090G for faster management of reordering and spare parts.

Usage and installation notes

To achieve correct assembly, it is important to check the thread compatibility with the components to be connected and ensure that the size 1"1/4 matches the line being worked on. During installation, operate carefully to avoid damage to the threads and ensure a clean fit.

Practical indications (generic)

• Check that the ends to be connected are clean and in good condition.
• Verify the alignment of the line before tightening to reduce stress on the fitting.
• In case of replacement, compare the type and size of the removed fitting with the new component.

Note: for choosing the correct fitting, always refer to the plant specifications and the components already installed. If size variants or different configurations are needed, it is advisable to select the fitting based on the threading and the line layout.
