Double M screw 1"1/2 in brass – DVGW – code: 0280H – Maestrini

Double M screw 1″1/2 in brass Maestrini (code 0280H)

The double M screw 1″1/2 in brass Maestrini, identified by code 0280H, is a component intended for plant engineering and fittings in the hydraulic and technical-professional field. It is designed for typical activities of maintenance, replacement and spare parts management, where correct part identification and consistency with existing installations are central aspects.

Component features and details

This double screw is offered in a configuration suitable for integration into hydraulic fittings and component systems, with attention to spare part recognizability and dimensional compatibility required by the system.

• Type: double-ended M screw
• Size: 1″1/2
• Material: brass
• Brand / supplier: Maestrini (MAESTRINI S.R.L. SOLE SHAREHOLDER COMPANY)
• Supplier product code: 0280H
• Indication in denomination: DVGW

Identification and traceability of the spare part

In technical contexts, the availability of a unique reference such as the code 0280H simplifies the selection of the correct component, reducing the risk of confusion between similar variants. This is particularly useful when working on existing systems, where replacing the removed part “by sample” or comparing with the bill of materials is the most reliable method.

Typical applications

The double M screw is normally used as a connecting/joining element in fittings and plant maintenance. The product is indicated for uses where a specific size is required 1″1/2 and where brass is specified by the design or system configuration.

• Maintenance and repair of hydraulic lines and fitting groups
• Replacement parts on existing installations, with verification through code and measurement
• Technical interventions in professional settings (workshop, plant engineering, maintenance)
• Onboard systems and nautical contexts, where spare parts management requires quick and consistent identification

Since system configurations can vary, it is advisable to base the choice on direct inspection of the component to be replaced and on the specifications of the system in which it will be installed.

Usage and installation notes

For a correct installation, it is important to verify in advance the correspondence between the component and the system. In particular, the term “double M screw” and the measurement 1″1/2 must be compatible with the expected configuration.

• Dimensional check: check the measurement 1″1/2 and the type required by the fitting or group being worked on.
• Comparison with the removed part: when possible, directly compare the existing component with the spare part.
• Code check: use the code 0280H as a reference for reordering and alignment with the bill of materials.
• Management in nautical contexts: in onboard systems, plan the intervention considering accessibility and system downtime, preparing the correct spare part before opening the circuit.
