1"1/4 Brass F-F Cone Seat Coupling – DVGW – code: *0340G – Maestrini

The F-F coupling with conical seat Maestrini in brass, size 1"1/4, it is a component designed to create threaded connections female-female in hydraulic and plant engineering fields. The presence of the conical seat it is indicated when the required coupling geometry includes this type of stop, aiming to achieve a neat and manageable connection even during intervention.

Identified by supplier product code *0340G, this coupling is a practical solution for technical installations where the possibility of disassembly and maintenance is a relevant aspect, including contexts such as’onboard systems (nautical) where clean layout and component accessibility aid in inspection and restoration operations.

Features and details

Type of fitting

• Configuration: spout F-F (female threading on both sides).
• Seat: conical seat, for couplings that require this geometry.

Material

• Material: brass.

Size and identification

• Size: 1"1/4.
• Brand: Maestrini.
• Supplier code: *0340G.

Typical applications

This nipple is suitable for threaded connections where a solution is needed female-female with conical seat, for example in:

• Hydraulic systems and connections between components with compatible threads.
• in civil or light industrial fields, where brass fittings are commonly used. in civil or industrial fields, where a component that is easy to handle during maintenance is useful.
• Onboard systems (nautical), when layout order and accessibility of fittings are important aspects.

The choice of the correct nipple always depends on the measurement, the type of seat and the compatibility with the counterpart components (fittings, valves, adapters, or other line elements).

Advantages

• Practical solution for F-F connections: useful when it is necessary to join two ends with female threading.
• Conical seat geometry: suitable for configurations where this type of coupling is required.
• Maintenance management: component indicated in installations where control or replacement interventions are expected.
• Brass material: common choice in hydraulic and plant engineering for fittings and connection components.
• Clear identification: Maestrini brand and code *0340G useful for reordering and traceability in the warehouse.

Usage and notes for selection

Checks before purchase

To correctly select the component, it is advisable to verify:

• Measure 1"1/4 in relation to the line and existing components.
• Type of seat (conical seat) and correspondence with the counterpart.
• Compatibility with the rest of the system and the intended application (layout, accessibility, need for disassembly).

Installation

Installation must be carried out by qualified personnel according to good engineering practices. In case of doubts about the compatibility of the conical seat or the correct configuration of the connection, it is advisable to compare the specifications of the counterpart component and the manufacturer's technical documentation.

Maintenance and spare parts management

In technical contexts (including nautical), the ability to quickly identify the spare part is an operational advantage: keep the reference Maestrini *0340G and the size 1"1/4 facilitates reordering and replacement in case of intervention.
