Heavy 3/4" washer in anti-corrosion brass – CR – DVGW – code: 7073E – Maestrini

Heavy anti-corrosion brass washer Maestrini (code 7073E)

The heavy 3/4″ washer in anti-corrosion brass Maestrini brass threaded rod – code 0210D code 7073E, is a technical small parts component designed for use in assemblies where a washer with a “heavy” body is useful, therefore more robust compared to standard washers. It is a solution suitable for contexts of hydraulics and fittings and, more generally, to assembly and maintenance activities where a more even distribution of the load on the tightening point is desired.

The declared material is brass with finish/manufacture anticorrosion (CR). The washer is offered in the format 3/4″, useful in combination with components and connections that require this size. The product is from the brand Maestrini, a well-known supplier in the plant engineering components sector.

Main features and details

, indicated for use as hardware in technical contexts where stainless steel material is preferred. The choice of material is an important element for the consistency of the assembly (screws, washers, accessories, and supports) and to reduce typical issues of mixed assemblies.

• Type: washer heavy
• Size: 3/4″
• Supplier product code: 7073E

Material and finish

• Material: brass
• Feature: anticorrosion (CR)

Typical applications

This washer is suitable for uses of assembly and maintenance where a more “substantial” washer is desired compared to a light version, for example to improve support during tightening or to protect the contact surface.

Usage contexts

• Hydraulic systems and fittings, where brass small parts are frequently used.
• Technical hardware for assemblies on metal components or on surfaces that require a wider and more stable support.
• Maintenance in humid or exposed environments, where a material choice oriented towards corrosion resistance can be useful.
• Onboard systems and nautical applications (in general), when brass components and reliable small parts for ordinary interventions are sought.

The size 3/4″ makes the washer suitable for configurations that adopt this size. For a correct match, it is good practice to check compatibility with the tightening element and with the support surfaces provided by your assembly.

Advantages during assembly

A heavy washer, compared to a standard washer, is often chosen for practical reasons related to stability and tightening management.

Load distribution and surface protection

• More stable support: the washer helps create a more regular interface between the tightening element and the surface.
• Reduction of risk of marks: helps limit the direct imprint of the tightening on the underlying part, especially on more delicate or finished surfaces.
• Maintenance support: useful when working on existing assemblies and wanting to restore correct support.

Material choice

• Brass: material widely used in hydraulics and fittings, suitable for many technical small parts applications.
• Anti-corrosion (CR): feature oriented towards a more peaceful use in contexts where humidity or exposure may be a factor.

Usage and operational notes

To achieve a neat and consistent assembly with the needs of the system or assembly, it is advisable to follow some general good practices.

General installation guidelines

• Size check: make sure that the washer 3/4″ is correctly matched to the fastening component and the intended seat.
• Surface inspection: clean and inspect the bearing surfaces to prevent residues or burrs from compromising alignment.
• Progressive tightening: perform tightening gradually, keeping the element aligned and checking the washer's support.
• Final inspection: after assembly, verify that the washer is properly seated and that there are no misalignments.

Compatibility and checks

The washer is described as heavy and at anti-corrosion brass (CR). For special applications (for example, systems with specific requirements or regulatory constraints), it is appropriate to refer to the manufacturer's documentation and your project's specifications.
