Hose holder in hexagonal bar M 1/2"x12 in anti-corrosion brass – CR – code: 7157D*12T – Maestrini

Hose holder in M 1/2"x12 hexagonal bar in anti-corrosion brass (CR) Maestrini

The hose holder in hexagonal bar M Maestrini is a fitting designed to neatly connect a line with male threading to a flexible hose via hose connector fitting. The construction in anticorrosion brass and the geometry in hexagonal bar makes it suitable for plant engineering and maintenance contexts where robust, easy-to-install components consistent with typical technical use are required.

This version is identified as CR and corresponds to the Maestrini code 7157D*12T, with size 1/2"x12. It is a solution recommended for those who want a catalog-recognizable component, easy to manage during procurement and replacement, and suitable for integrations or restorations on existing systems.

Features and construction details

Type of fitting

• Hose clamp for connection to flexible hose.
• Male fitting (M) threaded side.
• Hexagonal bar body, useful for wrench grip during assembly.

Material

• Anti-corrosion brass, chosen for applications where good long-term resistance in technical environments is sought.

Product identification

• Size: 1/2"x12
• Supplier code: 7157D*12T
• Brand/Supplier: Maestrini

Typical applications

The Maestrini hose connector is commonly used in plant engineering where it is necessary to transition from a threaded connection to a flexible hose connection. The hex bar configuration facilitates installation and maintenance operations, especially when working in technical spaces or on existing components.

Plant engineering and maintenance

• Localized maintenance and replacement of hose connector fittings on existing lines.
• Construction or upgrade of connections between threaded components and flexible piping.
• Use in contexts of onboard systems and related technical applications, where material choice and ease of assembly are important aspects.

When the hex bar is useful

The hexagonal shape of the body is a practical detail: it offers a stable grip with a wrench and helps control tightening during installation. This can be useful both during initial assembly and during disassembly and restoration operations.

Operational advantages

• Easier installation thanks to the body in hex bar, which facilitates the use of common tools.
• Neat solution to switch from male threading to hose fitting, useful in many system configurations.
• Anti-corrosion brass material, , suitable for technical environments where a durable and maintenance-friendly component is desired.
• Traceability through product code 7157D*12T, , useful for consistent reorder and replacements.

Usage and selection notes

Check measurements and system compatibility

Before purchase and installation, it is good practice to verify that the measurement 1/2"x12 is consistent with the component to be connected and the intended flexible hose. In case of replacement, also compare the geometry of the existing fitting and the available space.

Assembly

During installation, the hex bar allows tightening the fitting with a stable grip. For correct assembly, it is important to work carefully, avoiding forcing and respecting good practices for assembling threaded fittings and flexible hose connections.
