F-F 1/2" conical seat brass fitting – code: *0340D – Maestrini

1/2″ Maestrini brass F-F fitting with conical seat (code *0340D)

The female-to-female fitting (F-F) with conical seat Maestrini in brass, size 1/2″, it is a component designed for interventions where hydraulics and system maintenance a neat connection between elements with female connections is needed. The presence of the conical seat makes it suitable for configurations where this coupling geometry is required by the existing system.

Features and construction details

• Type: fitting F-F (female-female).
• Seat: conical (to be paired with components compatible with conical seat).
• Size: 1/2″.
• Material: brass (finish indicated as yellow brass in existing content).
• Brand / supplier: Maestrini.
• Product code: *0340D (useful for reorder and identification).

Why the conical seat is important

The wording “conical seat” identifies a specific coupling geometry. During replacement or restoration, it is essential to maintain the same seat type provided by the system: choosing a fitting with a different seat may require adaptations or lead to incorrect assembly. For this reason, the fitting *0340D is recommended when the system already has a conical seat connection and a consistent replacement is desired.

Typical applications

This fitting can be used in contexts of plant engineering and maintenance where it is necessary to connect two components with female connections, maintaining a clean and easily inspectable configuration. In particular, it can be considered for:

• Replacements of worn or damaged fittings with the same type (F-F, conical seat, 1/2″).
• Restorations existing lines and connections, when modifications to the system are to be avoided.
• Maintenance interventions on technical systems, including nautical/on-board contexts, where the correct identification of the replacement part is essential.
• Fittings and reorders of components in stock, thanks to the unique reference of the code *0340D.

NoteThe actual application depends on compatibility with the components already present (size, seat, and connection standard). In case of doubt, it is advisable to compare the existing part or the system documentation.

Usage and operational notes

For a correct installation, it is good practice to check before purchase and assembly:

• Sizeto confirm that the system requires 1/2″.
• Type of seat: ensure that the intended connection is actually conical seat.
• Compatibilityto compare the fitting with the component to be replaced (geometries, dimensions, and coupling standards).
• Spare part code: use *0340D as a reference to align order, bill of materials, and documentation.

In case of interventions on existing systems, it is advisable to operate carefully to avoid damaging the mating surfaces of the seat. If the system has particular configurations or non-standard components, evaluate the most suitable solution in advance before final assembly.

FAQ – Frequently Asked Questions

What is a conical seat F-F filler neck?

It is a fitting with female connections on both sides (F-F) designed for connections that require a conical seat. It must be paired with components compatible with the same seat type.

What is the size of this Maestrini spout?

The size indicated for this model is 1/2″.

What material is it made of?

The fitting is made of brass (yellow brass, as stated in existing content).

What is the purpose of code *0340D?

The code *0340D is the product reference useful for correctly identifying the replacement part, managing bills of materials, and facilitating reorder.

How do I check compatibility before purchase?

Check that the system requires the 1/2″ size, that the connection has a conical seat, and compare the component to be replaced (type of connection and geometries) with the fitting.
