90° Elbow F.F. 1/4" yellow – DVGW – code: 0090B – Maestrini

90° Elbow F.F. 1/4″ in yellow brass Maestrini (code 0090B)

The 90° Elbow F.F. 1/4″ in yellow brass Maestrini, code 0090B, is a fitting designed to make direction changes at 90° in systems where a connection is required female/female. It is a typical solution in plumbing and plant engineering, useful when space or the pipe route requires an orderly and compact deviation.

Features and construction details

This fitting is identified as 90° elbow with threads F.F. (female/female) and size 1/4″. The body is made of yellow brass, a material commonly used in fittings for plumbing systems due to its workability and widespread use in technical applications.

• Type: 90° elbow
• Connections: F.F. (female/female)
• Size: 1/4″
• Material: yellow brass
• Product code: 0090B
• Brand/Supplier: Maestrini S.r.l. Sole Shareholder Company
• Indication reported: DVGW

The elbow shape allows connecting two threaded sections while maintaining a sharp deviation, useful to avoid improper bends or makeshift solutions. The F.F. configuration is practical when joining elements with male ends or when inserting the fitting as an intermediate element between already prepared components.

Identification and coding

For orderly management of spare parts and bills of materials, the product is identified by SKU MAES00000001 and by the supplier code 0090B. In professional contexts, code matching helps reduce errors during reordering and maintain consistency between technical documentation and installed material.

Typical applications (hydraulics and plant engineering)

A 90° Elbow F.F. 1/4″ is normally used in systems and connections where it is necessary to change the line direction while maintaining a threaded connection. It is a versatile component, usable in many configurations, provided the size and thread type are consistent with existing components.

• Hydraulic systems and technical lines with threaded fittings
• Maintenance and replacement of worn or damaged fittings
• Route modifications in tight spaces or with space constraints
• Onboard systems (nautical) for reordering and rationalizing lines, where provided by the project

In general, this type of fitting is chosen when a clean and easily inspectable solution is desired, typical of threaded connections. The 1/4" size makes it suitable for small diameter lines and branches, always respecting the system specifications.

Operational advantages

• Direction defined at 90°: allows an orderly and repeatable change of route
• F.F. connection: useful as an intermediate element between components with male ends
• Compact size: suitable for interventions in technical spaces and system compartments
• Common material: yellow brass is common in fittings and facilitates the availability of compatible components for similar configurations
• Clear coding: code 0090B for simpler and more consistent reordering

Usage and installation notes

Before installation, it is good practice to check that size (1/4") and type of threading (F.F.) are correct with respect to the components to be connected. In case of replacement, also check the condition of the threads of the existing parts and the alignment of the line, to avoid mechanical stresses on the fitting.

• Compatibility check: check the size and thread standard required by the system
• Mounting: tighten appropriately avoiding forcing; ensure that the 90° orientation is the desired one
• Sealing: use a sealing system suitable for threaded connections and the intended fluid/system, according to usual procedures
• Inspection: after installation, perform the checks required by the system to verify the correct sealing of the connection

For applications in the nautical field or onboard systems, it is recommended to follow the instructions of the designer or the maintenance technician responsible for the system, choosing components consistent with the existing configuration and the installation practices adopted.
