Brass Round Tube — Precision Hollow Pipe for DIY, Modeling & Craft Projects

Whether you're building a scale model, fabricating a custom furniture piece, or need a reliable spacer for a mechanical assembly, finding a brass round tube in exactly the right diameter is often the hardest part. Machinists, hobbyists, pen turners, and makers all run into the same wall: hardware stores carry only a handful of sizes, leaving you to compromise on fit. This listing solves that with 32 OD sizes in a single product.

Each tube is a seamless brass hollow round pipe with an outer diameter (OD) ranging from 1.5mm (≈1/16") to 25mm (≈1"), a uniform wall thickness of 0.5mm, and a cut length of 500mm (≈19.7"). The inner diameter (ID) is always 0.5mm less than the OD on each side — for example, the 6mm OD tube has a 5mm ID. Material is standard C260 cartridge brass (CuZn30), known for its machinability, solderability, and warm golden finish.

Typical applications include scale model aircraft and train frames, telescope tube assemblies, pen turning blanks, DIY lamp and furniture hardware, jewelry findings, and small-bore fluid routing prototypes where a lightweight brass hollow tube for model making is needed. The 500mm length gives you enough material to cut multiple shorter pieces from a single order.

ℹ️ Compatibility Note: These are plain, unthreaded metric tubes. OD and ID dimensions follow metric standards. Verify your required OD and ID against the variant options before ordering — wall thickness is fixed at 0.5mm across all sizes.

✅ Key Features of These Brass Round Hollow Tubes

  • 📐 32 OD Sizes in One Listing — From 1.5mm (≈1/16") to 25mm (≈1"), covering the full range needed for precision DIY brass tubing projects without ordering from multiple suppliers.
  • 🔩 Consistent 0.5mm Wall Thickness — Uniform thin-wall construction across all sizes ensures predictable weight, flex, and cut behavior — ideal for brass hollow tube for model making and craft applications.
  • ✂️ Easy to Cut, Solder & Shape — C260 cartridge brass machines cleanly with standard tools, accepts lead-free solder readily, and can be bent with a tube bender without cracking at this wall thickness.
  • 🛡️ Natural Corrosion Resistance — Brass resists oxidation better than plain steel in typical indoor and moderately humid environments, reducing the need for protective coatings in most DIY and workshop settings.
  • 📏 500mm Working Length — Each piece is 500mm (≈19.7") long, giving you enough material to cut multiple sections per tube — useful for small-bore brass pipe projects requiring several identical pieces.
  • Smooth Golden Finish — The natural brass surface finish is clean and uniform, suitable for decorative applications, pen turning, jewelry hardware, and lamp components without additional finishing.

❓ Frequently Asked Questions

How do I choose the right OD size for my project?

Measure the opening or shaft your tube needs to fit around or inside. The OD (outer diameter) is the outside measurement. For example, if you need a tube that slides over a 4mm rod, choose an OD of 5mm (ID 4mm). All sizes are listed in millimeters — to convert, divide by 25.4 for inches (e.g., 10mm OD ≈ 3/8").

What is the wall thickness, and does it affect strength?

All tubes in this listing have a uniform 0.5mm wall thickness. While this is a thin-wall tube suited for lightweight structural, decorative, and precision applications, it is generally not recommended for high-pressure fluid lines. For heavier load-bearing use, a thicker-wall brass tube is typically advised.

Can these brass tubes be used outdoors or in humid environments?

Brass offers naturally good corrosion resistance compared to plain steel, making it suitable for moderately humid or indoor-outdoor environments. However, in highly corrosive or marine conditions, brass may develop a patina over time. A clear lacquer or sealant coat is generally recommended for prolonged outdoor exposure.

What thread or fitting standards are compatible with these tubes?

These are plain, unthreaded hollow tubes. They are compatible with standard metric fittings, compression fittings, or push-fit connectors sized to match the OD. For threaded connections, you would typically need to add a brass compression fitting or ferrule that matches your chosen OD. Contact us to confirm compatibility with your specific fitting.

Can I cut or solder these tubes?

Yes. Brass is generally easy to cut with a fine-tooth hacksaw, pipe cutter, or rotary tool, and it solders well with standard lead-free or silver solder. The 0.5mm wall thickness means a light touch is recommended when cutting to avoid deforming the tube.

What are the most common uses for these brass hollow tubes?

These tubes are commonly used in scale model making, RC aircraft frames, jewelry and craft projects, DIY furniture hardware, pen turning, telescope and optical instrument assembly, and small-scale plumbing or fluid routing prototypes.

How long is each tube, and can I order custom lengths?

Each tube is 500mm (≈19.7") long. Custom lengths are not available through this listing. If you need a specific length, the tubes can be cut to size using standard metalworking tools.
