90° Elbow F-F 1" yellow – DVGW – code: 0090F – Maestrini

90° 1" F-F Elbow Yellow Brass Maestrini (code 0090F)

The 90° 1" F-F elbow Maestrini, identified by code 0090F, is a fitting designed to create a deviation at 90° in a system, maintaining a configuration with female threading on both sides (F-F).

Features and details of the fitting

90° configuration and F-F connections

The fitting is a 90° elbow, useful when it is necessary to change the direction of the piping or connection path without resorting to bends or improvised solutions. The configuration F-F indicates that both connections are female, a common choice when connecting elements with male ends or when working with adapters and nipples already present in the system.

Nominal size

The indicated measurement is 1". When purchasing and installing, it is important to verify compatibility with the threading and the components already installed, to avoid dimensional incompatibilities.

Brand and product identification

• Brand / Supplier: Maestrini S.R.L. Sole Proprietorship
• Supplier product code: 0090F
• Type: 90° Elbow
• Connections: Female – Female (F-F)
• Size: 1"

When managing spare parts or replicating an existing configuration, the reference to the code 0090F is particularly useful to reduce ambiguity and speed up the selection of the correct component.

Typical applications

A 90° F-F elbow is used in many plumbing situations where space or layout requires a sharp change of direction. In a technical context such as nautical or industrial, it can be useful in various areas of the system, always respecting the specifications of the system in which it is installed.

Plant engineering and maintenance

• Creating deviations on existing lines, when modifying the path of a pipe.
• Restoration of connections in case of component replacement or repairs.
• Space optimization in technical spaces, where a change of direction allows for a tidier installation.

Simpler spare parts management

The presence of a product code clear (0090F) and the indication of the size (1") help reduce errors during reordering, especially when managing multiple fitting variants (different sizes or threading configurations).

Usage and installation notes

For correct assembly, it is advisable to carefully check compatibility with the threading and with the components upstream and downstream of the fitting. In particular, before installation:

• check that the size 1″ matches that requested by the system;
• verify that the configuration F-F is consistent with the fittings or adapters present;
• ensure that the line path allows a deviation at 90° without forcing the connections.

In case of replacement, it can be useful to compare the removed component with the new fitting, paying attention to geometry and attachments. If the system is part of a larger system (for example in a technical room), it is good practice to operate in an orderly manner and maintain traceability of the installed components, also through reference to the code 0090F.
