Heavy flange nut 1/2" (locknut) – code: 0069D – Maestrini

Heavy flanged nut 1/2″ (ring) Maestrini – code 0069D

The heavy flanged nut 1/2″ (ring) Maestrini, code 0069D, is a component intended for applications in hydraulics and fittings where a clamping element with flanged geometry is required. The “ring” configuration makes it suitable for assembly and maintenance interventions in plant engineering, with a typical setup of components used on lines and technical connections.

Identification

• Type: heavy flanged nut (ring)
• Size: 1/2″
• Supplier product code: 0069D
• Supplier: MAESTRINI S.R.L. SOCIETA’ UNIPERSONALE
• SKU: MAES00000219

Shape and function (general description)

A flange nut integrates a flange that can help distribute the clamping load over the contact area. The term “ring” refers to its use as a locking/clamping element in assemblies where the shape of the nut and its seating are part of the design solution. In the absence of further material or standard specifications, the choice should be made mainly based on measurement e code, verifying the match with the existing component or with the plant bill of materials.

Typical applications

This heavy flanged nut is part of the components used in the field of , is a practical component for processing and assembly in the and in the management of fittings and technical connections.

• Plant maintenance: replacement of worn or damaged small parts on existing connections.
• Assemblies and restorations: interventions on fittings and joints that require a flanged nut (ring) of the correct size.
• Technical spare parts: replacement of components identified by supplier code, useful to maintain consistency with the original configuration.

Usage and purchase notes

For correct use it is essential to verify the size 1/2" and the match with the component to be replaced. In plant engineering (especially on onboard systems), small differences in type or profile can make a replacement unsuitable even if the size appears similar.

Verification tips before ordering

• Check the code: if your component shows or requires 0069D, this is the most reliable indication.
• Check the measurement: make sure the connection is actually 1/2″.
• Compare the shape: the term “ferrule” and the presence of flange must match the existing part or the planned drawing/spare part.
• Usage context: if the nut is part of a fitting or a larger assembly, evaluate the whole (fits and clearances) before replacement.

Installation notes (generic)

During assembly, work with appropriate equipment and according to the procedures provided by your plant. If you are working on a hydraulic line, ensure that the circuit is in suitable conditions for maintenance (for example, without pressure and with safe access to the intervention point), following the operational practices of your context.

Support for identification

If you have doubts about the compatibility of the spare part, it is useful to have available: photos of the component, indications present on the part, and reference to code 0069D. This helps reduce selection errors and speeds up the verification of the correct component.

FAQ – Frequently Asked Questions

What is the code of the Maestrini heavy flange nut?

The supplier product code is 0069D. It is the most useful reference to uniquely identify the spare part.

What size is this flange nut (ring)?

The indicated size is 1/2″. Before purchase, it is advisable to verify that it matches the connection or the component to be replaced.

Is this product suitable as a replacement for plumbing systems?

Yes, it falls under the plumbing and fittings category and is indicated as a clamping component (nut) in compatible assemblies. Compatibility must be verified by size and type.

How can I check if it is the right nut for my fitting?

Compare code 0069D and size 1/2″ with the plant documentation or the existing part, also checking for the presence of the flange and the “nut” type.
