Model Description

This is a threaded dust plug for small LPG/propane gas bottles, designed specifically to fit 3 kg – 5 kg gas tanks. The plug screws directly into the bottle’s valve outlet, covering the connection when the regulator is removed.

Its primary purpose is to protect the valve connection from dust, dirt, insects, and moisture, helping to keep the threads and sealing surfaces clean during storage or transport. By preventing contamination, the plug reduces wear on the valve and helps ensure a proper seal when reconnecting the regulator.

The plug features a male threaded section that matches the gas bottle outlet and a hand-grip top with raised fins, allowing easy installation and removal without tools. The compact, durable design makes it ideal for camping gear, caravans, BBQ setups, and general LPG storage.

Design Concept

The design focuses on simplicity, reliability, and ease of use:

Threaded Protection

The threaded section ensures a secure fit in the gas bottle valve, preventing debris and moisture from entering sensitive areas of the connection.

Tool-Free Operation

The enlarged top with ergonomic grip fins allows the plug to be tightened or removed by hand, even with gloves.

Compact & Robust Geometry

The smooth, rounded body minimizes snagging during transport while maintaining sufficient wall thickness for strength and durability.

3D-Print Friendly

The model is optimized for FDM printing with no supports required. It prints cleanly in common materials such as PLA, PETG, or ABS, making it easy to reproduce and customize.

Non-Pressurized Safety Use
This plug is intended only as a dust and moisture protector, not as a pressure-retaining or gas-sealing component, keeping the design safe and purpose-specific.

Overall, the design provides a practical, reusable solution for keeping LPG/propane gas bottle connections clean, extending the lifespan of the valve and improving reliability during use
