Typical applications in the nautical field

An adjustable expansion plug can be used in various operational situations, especially when a practical and reversible closure is needed. In particular, it can be useful on:

• technical holes and passages prepared on hulls, bulkheads, or fitting components;
• service openings used during maintenance or inspections;
• situations where a tidy closure is desired without permanent interventions.

The choice of the correct plug always depends on the hole geometry, seat thickness, and the intended use. If the opening is subject to particular stresses or specific conditions, it is advisable to carefully evaluate the application.

Operational advantages

Adjustment and convenience

The expansion principle allows you to position the plug and adjust the tightening easily, making it suitable for applications where quick intervention is useful. The presence of the lever facilitates insertion and removal operations, especially when working in tight spaces or with limited access.

Neat solution for service closures

In many nautical installations, the need to close a hole can be related to setup phases or periodic interventions. An adjustable plug allows managing these needs with a dedicated component, avoiding makeshift solutions and maintaining a cleaner appearance of the system or the affected area.

Construction in chrome-plated brass

The body and lever in chrome-plated brass are an important detail for those looking for a metal component with a chrome finish. In the nautical field, the choice of materials is central: beyond aesthetic needs, consistency with other installed elements and usage conditions matters.

Use and notes

Check size and seat

Before installation, verify that the hole is actually 22 mm and that the seat is clean. Residues, burrs, or irregularities can affect the correct positioning of the plug and the stability of the closure.

Installation and removal

• Insert the plug into the hole ensuring it is properly aligned.
• Drive the lever to achieve expansion and locking.
• For removal, return the lever to the unlock position and pull out the plug.

Operating methods may vary depending on the installation configuration and the accessibility of the mounting point.

Compatibility and accessory choice

For specific applications, variants or related components may exist (for example, dedicated bushings in different materials). If you are configuring a system or need to replace an existing component, it is advisable to refer to the code 18.533.00 and the size 22 mm to avoid incompatibilities.

Purchase advice for spare parts and maintenance

For efficient management of onboard spare parts, note SKU and supplier code and keep them together with the boat or system documentation. In case of doubts about size or application, it is preferable to check directly at the installation point before ordering.
