Brass 3/8" square head M plug - code: 0290C - Maestrini

3/8″ square head M plug in brass Maestrini (code 0290C)

The 3/8″ square head M plug in brass Maestrini, code 0290C, is a component designed for threaded end closure in the hydraulic and plant engineering field. The realization in brass and the square head make it a practical solution when it is necessary to complete or secure a line, a fitting, or a preparation point, maintaining a neat and professional setup of the system.

In technical contexts such as nautics shape and the’onboard systems, the availability of reliable plugs and closures is useful both during installation and maintenance interventions. This plug falls into that category of “essential” small parts that help manage branches, predispositions, and inspection points, preventing them from remaining open or exposed.

Features and construction details

The product is identified by the Maestrini code 0290C and is described as M plug with square head and 3/8″ threading, made of brass. The configuration with a square head is typical of plugs designed to be tightened and removed with common tools, facilitating operations in technical spaces and plant compartments.

• Size: , in the
• Material: brass
• Brand: Maestrini
• Product code: 0290C

Square head: why it is useful

The square head is a functional choice for closure small parts: it offers a defined gripping point and allows controlled tightening with suitable wrenches. In practice, it helps to work more easily during:

• installations and completions of lines and fittings;
• ordinary maintenance interventions;
• temporary closures during tests or plant modifications.

Typical applications (nautical and plant engineering)

This plug is suitable for applications where it is necessary to close a threaded connection 3/8″. In nautical and plant engineering contexts, it can be used at various points of the system, depending on the configuration and service requirements.

Where it can be used

• End closure on fittings or prepared components.
• Management of branches not used or awaiting connection.
• Restoration and maintenance of lines, when it is necessary to isolate a point of the system.
• Fittings and refitting, to complete installations and keep connection points orderly.

Advantages in use

Although it is a simple component, a properly selected plug contributes to the overall quality of the installation. The Maestrini M plug 0290C offers a linear and professional solution for closing threaded connections, with a setup suitable for technical contexts.

Strengths

• Practical format for closures and preparations on 3/8″ threaded connections.
• Ottone; material commonly used in fittings and hydraulic components.
• Square head for a clear grip during assembly and disassembly.
• Unique coding (0290C) useful for reorders, scheduled maintenance, and spare parts management.

Usage and operational notes

To achieve a neat and consistent result with the system, it is advisable to proceed carefully during the selection and assembly phase. Being a threaded plug, correct compatibility depends on the matching of the thread and the condition of the seat on which it is installed.

General indications

• Preliminary check: check the size and type of thread of the point to be closed.
• Seat check: ensure that the thread is clean and in good condition.
• Mounting: screw in carefully, avoiding forcing that could damage the thread.
• Maintenance: in case of frequent disassembly, periodically inspect the condition of the thread and the plug.

Why choose the correct code

In a professional context, identification through product code simplifies spare parts management and reduces the risk of errors during procurement. If you are standardizing onboard small parts or preparing a maintenance kit, reporting the code 0290C helps maintain consistency between installation and spare parts.
