Fuel deck filler cap 50 mm – code: 20.467.01 – Osculati

Osculati fuel deck cap with neck Ø 50 mm (code 20.467.01)

The fuel deck cap Osculati is a deck accessory designed to create a neat and functional refueling point. This version, identified by the code 20.467.01, is designed for installations with neck Ø 50 mm and stands out for the solution on thread, which keeps the deck surface clean and free of unnecessary protrusions.

The construction features a flush opening handle (also integrated) and a safety chain to reduce the risk of losing the cap during operations. It is suitable for nautical applications where a component with attention to detail and consistent with a professional setup is desired.

Features and construction details

Flush design and integrated opening

The cap is completely flush and includes a flush opening handle. This configuration is particularly appreciated on deck because it helps maintain a smooth profile, facilitating cleaning and reducing the perceived bulk in the passage area.

Safety chain

The cap is supplied with safety chain, a practical detail during refueling and maintenance activities: it allows the cap to remain attached to the body of the filler neck, preventing it from being placed in unsuitable areas or accidentally falling.

New version with micro-cast cap

This is the new version with micro-cast cap. Investment casting is a construction solution used to obtain components with a refined finish and precise geometries, in line with the use on deck fittings.

Fitting: straight or angled

The product is available with:

• straight fitting tube;
• 45° angled fitting tube relative to the vertical.

The version with angled fitting is recommended when the refueling deck is inclined, to facilitate alignment with the piping and installation in spaces where the deck geometry does not allow a perfectly vertical mounting.

Reported dimensions

• Neck Ø: 50 mm
• Flange Ø: 80 mm
• Type: FUEL

Typical applications in the nautical field

The boarding fuel cap is used as an access point for refueling operations, integrating into the deck or a dedicated surface. It is a suitable choice in various contexts, for example:

• refitting and replacement of an existing cap with a flush model;
• new installations on pleasure or work boats, where a neat and easily manageable component is desired;
• setups where it is useful to be able to choose between straight fitting and angled fitting depending on the inclination of the mounting surface.

The choice of version (straight or angled) mainly depends on the arrangement of the piping and the angle at which the nozzle must connect to the system.

Practical advantages

Clean integration into the deck

The solution on thread contributes to a neater aesthetic and functional result. In many installations, a flush cap is preferred to maintain a more linear surface and to reduce protruding elements.

Simpler handling during refueling

The flush handle allows opening without resorting to improvised solutions, while the chain helps keep the cap under control during operations.

Installation flexibility

The availability of 45° angled fitting (as an alternative to the straight fitting) is an advantage when the mounting surface is not perfectly flat or when the piping requires an angled setup. In these cases, the inclination can make the installation more consistent with the geometry of the boat.

Usage and notes for selection

Check diameter and configuration

Before purchasing, it is advisable to check:

• the neck diameter required by the system (in this version Ø 50 mm);
• the available space for the flange (indicated as Ø 80 mm);
• if the mounting surface is inclined: in this case the version with 45° angled fitting.

Installation

The installation of components related to the fuel circuit requires attention and expertise. In case of doubts about compatibility with your configuration or the choice between straight and angled fittings, it is advisable to compare the measurements and layout of the system before installation.
