Double M screw 3" in CR anti-corrosion brass – code: 7280M – Maestrini

Double M screw 3″ in CR anti-corrosion brass Maestrini (code 7280M)

The double M screw 3″ Maestrini, code 7280M, is a component in CR anticorrosion brass designed for use in hydraulic and fitting applications, where materials suitable for environments subject to humidity and corrosive agents are required. The “double screw” format makes it suitable for assembly, connection or restoration interventions on systems and accessories compatible with the threading provided by the system in use.

Material: CR anticorrosion brass

The component is made of CR anticorrosion brass, a typical choice for hydraulic and fitting applications where a metallic material with good resistance in challenging environments is desired. In system engineering (including nautical), brass is often preferred for its versatility and ease of integration with many fitting configurations.

Type: double M screw

The wording double-ended M screw identifies a connecting element with “double” geometry, used when it is necessary to create a union or coupling between prepared parts. During replacement or maintenance, this type is useful for restoring existing connections while maintaining the system’s construction logic.

Size: 3″

The indicated measurement is 3″. For correct selection, it is advisable to verify the match with the size required by your system or the component to be paired, especially in the presence of specific configurations or pre-existing adaptations.

Product code: 7280M

The reference Maestrini 7280M is useful for quick identification of the replacement, for assistance requests or to align the order with bills of materials and internal technical documentation.

In summary

• Product: Double M screw
• Size: 3″
• Material: CR anticorrosion brass
• Brand: Maestrini
• Code: 7280M

Typical applications

The Maestrini double M screw can be used in contexts of hydraulics and fittings and, more generally, in activities of and where brass components are expected and where the 3″ size is consistent with the installation. In nautical and onboard system engineering, anti-corrosion brass components are commonly chosen for interventions on lines and accessories subject to harsh environmental conditions.

• Maintenance and restoration of connections on hydraulic systems
• Installations on fittings compatible with the “double screw” type”
• Replacement parts identified by Maestrini code 7280M

Operational advantages

• Material suitable for exposed environments: CR anti-corrosion brass is a typical solution when a metal component designed for humid or potentially aggressive environments is desired.
• Identifiable spare part: the code 7280M It facilitates warehouse management, replacement, and alignment with bills of materials or plant diagrams.
• Functional format: The “double screw” configuration is useful when a joining/coupling element is needed in installations consistent with this type.

Checks before installation

For correct assembly, it is good practice to check:

• Size 3″ actually required by the system or the fitting to be matched
• Type (double screw M) consistent with the existing configuration
• Product code (7280M) in case of replacement of an already installed component

Compatibility and matches

Compatibility depends on the system being worked on (fittings, threads, and connected components). In the absence of further dimensional data or declared standards, it is recommended to compare the component with the one to be replaced or with the specifications of your system before purchase.

Instructions for purchase and spare parts management

To speed up selection, always include in the request:

• Brand: Maestrini
• Code: 7280M
• Description: double screw M 3″ in CR anti-corrosion brass

This information helps reduce ambiguity during reordering and maintain consistency between spare parts and installation.
