1" Flanged Nut – DVGW – code: 0070F – Maestrini

1″ Maestrini flange nut (code 0070F) – component for fittings and plant engineering

The 1″ Maestrini flange nut, Osculati code 0070F, is a component intended for assembly and tightening in system contexts, where a fastening element with flanged geometry is required. In technical contexts such as’onboard systems, hydraulics, and maintenance, choosing spare parts and small components consistent with the rest of the system is essential for orderly work and quick interventions.

Identification

• Product: Flange nut
• Size: 1"
• Brand / Supplier: Maestrini (MAESTRINI S.R.L. SOLE SHAREHOLDER COMPANY)
• Supplier product code: 0070F

What does “flange nut” mean”

A flange nut it is a nut equipped with an integrated flange, designed to offer a larger bearing surface compared to a standard nut. In many applications, this helps distribute contact on the mated part and makes some assembly operations more practical, especially when working on components and fittings where support and alignment are important aspects.

Typical applications

The flange nut is a technical small parts element used in various contexts of hydraulics and fittings. In particular, it can be used in activities such as:

• Assembly of fittings and connections that require controlled and repeatable tightening.
• Maintenance and replacement of worn or missing components, in systems where the size is present 1".
• Onboard systems (nautical) and technical systems, when using components compatible with the series and manufacturer.
• Workshop interventions or on site, where it is useful to have spare parts identified by code and brand to reduce procurement errors.

For proper selection, it is good practice to compare the size and type of nut with the component on which it must be mounted (fitting, seat, threaded part), avoiding “eyeball” substitutions when the system requires dimensional consistency.

Checks before purchase

To purchase the correct component, it is recommended to verify:

• Size 1″ actually required by the application (as indicated on the existing component or on the system bill of materials).
• Code 0070F as a direct reference to avoid ambiguity between similar versions.
• Compatibility with the fitting or with the threaded part on which it will be installed (profile and pitch are not indicated in this sheet and must be checked on the original component or technical documentation).

Mounting instructions (generic)

In the absence of specific manufacturer instructions, some general good practices apply:

• Ensure that the mating surfaces are clean and free of residues that could compromise the seating.
• Initially screw in by hand to reduce the risk of thread damage.
• Complete the tightening with suitable tools, respecting the indications of the system or the fitting manufacturer.
• In case of doubts about sealing and compatibility, refer to a qualified technician or the documentation of the system in which the component is installed.

Spare parts and maintenance

When replacing a flange nut, it is also useful to check the condition of the mating parts (seat, fitting, male thread) to avoid installing a new component on damaged surfaces. For spare parts management, the reference Maestrini 0070F allows faster reordering and reduces the risk of incompatibilities due to generic codes.

FAQ – Frequently Asked Questions

What is the size of the Maestrini flange nut in this sheet?

The indicated size is 1″.

What is the product code of the Maestrini flange nut?

The supplier product code listed is 0070F.

Is this product suitable for onboard systems?

It is a small parts component for hydraulics and fittings and can be used in system contexts, including onboard systems, provided it is compatible with the fitting and system configuration.

What advantage does a flange nut offer compared to a standard nut?

A flange nut integrates a flange that increases the bearing surface, making some installations more practical and contributing to a wider support on the mated part.

How do I check compatibility before purchase?

It is recommended to compare the 1″ size, code 0070F, and the type of nut with the existing component or the plant documentation, also checking the threading and the coupling with the fitting.
