90° Elbow F.F. 1"1/2 in yellow brass – DVGW – code: 0090H – Maestrini

90° Elbow F.F. in yellow brass Maestrini (code 0090H)

The 90° elbow F.F. 1"1/2 in yellow brass Maestrini, code 0090H, is a fitting designed to make right-angle direction changes in system lines, maintaining an orderly and easily inspectable configuration. The 90° geometry allows practical management of passages and spaces, especially when space is limited or when a “clean” piping route is desired.

In the technical field (plant engineering, maintenance, and onboard applications), choosing the right fitting is essential to simplify installation and facilitate any subsequent interventions. This Maestrini model combines a construction in yellow brass with a configuration F.F. (female/female), useful when connecting elements with male ends or threaded components compatible with the intended connection.

Features and construction details

Type of fitting

• Shape: elbow for 90° for right-angle direction change.
• Connections: F.F. (female/female).
• Size: 1″1/2.
• Product code: 0090H.
• Brand / supplier: Maestrini.

Material

The fitting is made of yellow brass, material commonly used in fittings for systems due to its workability and good suitability for use in maintenance and system contexts. The finish and construction are oriented towards technical use, where reliability over time and ease of assembly matter.

Identification and traceability

For an orderly management of warehouse and maintenance, this fitting is identified by:

• SKU: MAE0000012345
• Supplier code: 0090H

These references help to quickly reorder the same item and maintain consistency between the bill of materials, spare parts, and interventions.

Typical applications (plant engineering and maintenance)

A 90° F.F. elbow is normally used when it is necessary to divert the path of a line without resorting to bends or curves in the pipe. In particular, it can be useful in:

• Hydraulic systems and distribution lines where a sharp change of direction is needed.
• in civil or light industrial fields, where brass fittings are commonly used. in machine rooms, lockers, or technical compartments, where the order of the pipes facilitates inspection.
• Maintenance and retrofit: replacements or modifications of existing sections, when you want to restore a correct geometry of the circuit.
• Onboard systems (nautical context): organization of passages and management of space in often constrained areas.

The configuration female/female it is practical when connecting two male elements or when the project foresees the use of threaded nipples/adapters (to be selected based on the plant's needs).

Operational advantages

Space management and plant order

The 90° elbow allows setting a defined path for the piping, useful for:

• reducing interference with other components;
• maintaining a more linear and readable layout;
• facilitating access during inspections and maintenance.

Practical solution for threaded connections

The choice of a fitting F.F. can simplify some assembly configurations, especially when working with components already equipped with male ends or dedicated adapters. During design or replacement, this helps maintain consistency among the various elements of the line.

Usage, installation notes, and best practices

To achieve correct assembly and reduce the risk of issues during operation, it is good practice to follow some general guidelines (always to be adapted to the type of plant and the installer's procedures):

Preliminary check

• Size check: check that the size 1″1/2 be consistent with the line and the components to be connected.
• Thread check: ensure that the threads of the coupled components are compatible and in good condition.
• Visual inspection: check that the fitting shows no transport damage or signs that could compromise the coupling.

Assembly

• Alignment: position the elbow to avoid mechanical stresses on the line; a fitting should not “force” the pipe or connected components.
• Sealing: use sealing systems suitable for the type of threading and the intended application, following industry practices and the technician's instructions.
• Tightening: tighten with care, avoiding excesses that could damage threads or mating surfaces.

Maintenance and replacement

In case of subsequent interventions, the presence of a well-positioned 90° elbow can make it easier to disassemble sections of the line and access components. In onboard contexts or compact systems, planning fittings in an orderly manner helps reduce downtime and improve system readability.
