Heavy 1/2" washer in anti-corrosion brass – CR – DVGW – code: 7073D – Maestrini

Heavy-duty anticorrosion brass washer Maestrini 7073D (1/2″)

The heavy-duty 1/2″ anticorrosion brass washer Maestrini, code 7073D, it is a technical small part designed for use in hydraulic and fitting fields. The choice of’anticorrosion brass makes it suitable for installations where a material traditionally used in plant componentry is sought, with attention to durability over time in maintenance and assembly contexts.

This washer belongs to the category of “heavy” washers, a type commonly adopted when a larger bearing surface than a standard washer is desired, useful for distributing the load and improving tightening stability in many practical applications.

Product features and details

Identification and main data

• Product: Heavy washer
• Size: 1/2″
• Material: anticorrosion brass
• Supplier product code: 7073D
• Brand / supplier: Maestrini (MAESTRINI S.R.L. SOLE SHAREHOLDER COMPANY)

“Heavy” construction: what it means in practice

The wording heavy identifies a washer designed to offer a more “robust” support compared to light solutions. During assembly, this approach can be useful when you want to:

• better distribute the tightening pressure on the contact surface;
• reduce the risk of marking or deforming the support point (depending on the material being worked on);
• achieve a more stable tightening in assemblies subject to periodic maintenance.

In the absence of further dimensional data, it is recommended to check compatibility with your own bolts/fittings based on the nominal size 1/2″ and the installation requirements.

Anti-corrosion brass

The’anticorrosion brass is a material frequently chosen in plant and fitting components, especially when a metallic solution suitable for technical contexts and usage conditions where corrosion resistance is an important selection criterion is desired. The Maestrini 7073D washer fits this usage logic, being suitable as a support and load distribution element in hydraulic assemblies.

Typical applications

This washer is suitable for general use in hydraulics and fittings, where a heavy brass washer can be used as a support component in assembly, tightening, and maintenance operations. In a technical context (including nautical/onboard plant engineering), it can find application in many operational situations, for example:

• assemblies with bolts or threaded elements where a more uniform load distribution is desired;
• maintenance interventions on fittings and plant components, when replacing small parts;
• installations where a brass metal washer is preferred for consistency with other components of the assembly.

The choice of the correct washer always depends on the type of coupling, the bearing surfaces, and the installation conditions: in case of doubt, it is advisable to compare the nominal size and the code 7073D with the bill of materials or with the removed spare part.

Operational advantages

• Tightening support: the “heavy” type is commonly appreciated for the greater stability of the support in many mounting applications.
• Common technical material: the’anticorrosion brass it is a recurring choice in components for systems and fittings, useful when a metal element suitable for maintenance contexts is desired.
• Identifiable spare part: the Maestrini code 7073D facilitates the identification of the component during reorder and spare parts management.
• Integration in hydraulic small parts: simple but essential component to correctly complete many assemblies with threaded elements.

Usage and installation notes

General indications

The washer is normally placed between the fastening element (for example nut or screw head) and the bearing surface, with the aim of improving load distribution. For a neat and functional result:

• check that the contact surfaces are clean and free of burrs or residues;
• check the consistency of the size 1/2″ with the bolts or with the component being worked on;
• in case of replacement, compare the new washer with the removed one (“heavy” type, material and dimensions).

Compatibility and spare part selection

For specific applications, compatibility depends not only on the nominal size but also on the geometries of the assembly and the type of coupling. If you are purchasing the washer as a spare part, the most reliable reference is the code 7073D from the manufacturer. Maestrini.

Storage and warehouse management

As with metal small parts, it is advisable to store the component in a dry and orderly place, keeping the labeling with code and measurement to speed up maintenance and reorder activities.
