F.F socket conical seat 3/8" brass – DVGW – code: *0340C – Maestrini

Maestrini brass 3/8″ conical seat F.F nipple (code *0340C)

The 3/8″ conical seat F.F nipple Maestrini, code *0340C, is a fitting in brass designed to create neat and reliable connections in plant engineering. The configuration F.F (female/female) with conical seat makes it suitable for installations where a precise coupling between threaded components is desired, with a sealing geometry typical of fittings with conical seat.

Brass: a practical choice for plant engineering

The’brass is a material commonly used in fittings for its workability and widespread use in many hydraulic applications. In maintenance, the presence of brass components often facilitates replacement management and integration with fittings and accessories of the same family.

Usage contexts

• Hydraulic systems and service lines where threaded connections in 3/8″ size are present
• Onboard systems (nautical), for fitting work and connection reorganization
• Maintenance and repair of sections with fittings with conical seat
• Technical setups where a compact and easily inspectable component is desired

When to choose a conical seat F.F nipple

The choice of a nipple female/female is typical when two male elements need to be joined or when a junction point is to be inserted between already prepared components. The conical seat is instead a useful indication for those working on systems that adopt this type of coupling: maintaining the same sealing geometry helps preserve consistency and ease of system management.

Strengths in installation and maintenance

• Functional format: essential component for joints and fittings on 3/8″ threads
• Conical seat geometry: useful for maintaining consistency with fittings of the same type present in the system
• Brass: material widely used in fittings, suitable for technical and maintenance contexts
• Clear identification: code *0340C to facilitate reordering and spare parts management
• Maestrini Brand: well-known reference in the fittings and plant engineering sector

System and spare parts consistency

In a professional context, a often decisive aspect is the standardization of components: using consistent fittings by type (F.F), seat (conical) and size (3/8″) simplifies inspection, procurement and stock management. This nozzle is well suited to be included in a bill of materials or a spare parts kit for quick interventions.

Practical indications

• Preliminary check: check that the size is actually , in the and that the system uses fittings with conical seat.
• Coupling: ensure that the contact surfaces are clean and free of residues that could interfere with proper closure.
• Maintenance: during interventions on existing systems, also inspect adjacent components to avoid leaving worn or inconsistent parts in place.
• Spare part: for reordering and traceability, refer to the code *0340C and the brand Maestrini.

Important note

The sealing methods and any necessary accessories depend on the overall system configuration and the coupled components. If the application requires specific requirements or documentary checks, consult the manufacturer's instructions and the technical procedures adopted during installation.

FAQ – Frequently Asked Questions

What does F.F. filler neck mean?

F.F indicates that the fitting has both ends with female threading (female/female), useful for connecting components with male ends or for creating a junction between threaded elements.

This nozzle has a conical seat: what does it imply?

The conical seat identifies a coupling geometry typical of certain fittings. It is important to verify that the component to be connected is also designed for a conical seat, in order to maintain consistency with the system.

What is the size of the fitting?

The size indicated for this nozzle is 3/8″.

What material is it made of?

The nozzle is made of brass, a material commonly used in fittings for plumbing systems and technical applications.

What is the product code for reordering?

The supplier product code is *0340C (Maestrini). Using it as a reference makes spare parts management and reordering easier.
