Brass Tube Brass Pipe 300mm Length — 0.5mm Wall, OD 1.5mm to 19mm

Measure the opening or shaft your tube needs to fit over or inside. For a slip fit, choose an OD slightly smaller than the receiving hole. For a press fit, choose an OD equal to or just above the hole diameter. As a quick reference: 6mm OD ≈ 1/4", 12mm OD ≈ 1/2", 19mm OD ≈ 3/4". When in doubt, order one size up and one size down to test fit before committing to a larger quantity.

All tubes in this listing have a 0.5mm wall thickness on each side. To find the inner diameter, subtract 1mm from the outer diameter you select. For example: a 6mm OD tube has an ID of approximately 5mm; a 10mm OD tube has an ID of approximately 9mm. If your application requires a tight ID tolerance, contact us to confirm before ordering.

Brass alloy generally offers tensile strength in the range of 300–500 MPa depending on temper and alloy composition. At 0.5mm wall thickness, these tubes are well-suited for light structural, decorative, and hobby applications — such as RC frame members, model building columns, and jewelry components. They are not intended for high-pressure hydraulic lines or heavy structural load-bearing use. Contact us if you need to confirm suitability for a specific application.

Brass is naturally corrosion-resistant and typically performs well in moderate outdoor and humid conditions. Over time, brass may develop a patina (a natural oxidation layer) which can be left as a protective finish or polished away with brass cleaner. For prolonged outdoor exposure or marine environments, applying a clear lacquer or sealant is generally recommended to maintain the original appearance and slow patina development.

These are plain, unthreaded round tubes. They are compatible with standard metric compression fittings, push-fit connectors, and collets sized to match the outer diameter you select. For threaded connections, an external die can typically be used to cut metric threads onto brass tube. Always confirm fitting compatibility with your specific connector or coupling before ordering, as tolerances vary by manufacturer.

Yes — brass is one of the most workable metals for hobbyists and small-shop fabricators. These tubes can generally be:

• Cut with a rotary tube cutter or fine-tooth hacksaw/jeweler's saw
• Soldered with standard lead-free or silver solder using a torch or soldering iron
• Bent using a tube bender or close-fitting spring mandrel (important at 0.5mm wall to prevent kinking)
• Drilled and filed with standard HSS drill bits and needle files

No CNC or specialized equipment is required for most hobby applications.

For RC aircraft and scale model making, tube sizing is typically driven by the axle, rod, or structural member the tube must interface with. Sizes in the 2mm–8mm OD range are most commonly used for RC linkages, pushrods, and lightweight frame members. Larger ODs (10mm–19mm) are more commonly used for structural columns, antenna mounts, or decorative elements in architectural scale models. If you're unsure, check your model's plans or the diameter of the rod or shaft the tube needs to slide over.

Each order includes 1 piece of the selected outer diameter variant. If you need multiple pieces or multiple sizes, simply add each variant to your cart separately or adjust the quantity. Contact us if you need larger quantities — bulk pricing may be available.
