Brass Round Tube — Precision 1mm Wall Hollow Tubing for DIY, Modeling & Fabrication

Finding a brass hollow tube in exactly the right diameter shouldn't mean ordering from overseas and waiting weeks. Whether you're a hobbyist building scale models, a maker fabricating a custom bracket, or a technician routing a small fluid line, having the right OD-to-ID ratio on hand is the difference between a clean fit and a frustrating workaround.

Each listing is for one brass round tube with a uniform 1mm wall thickness, available in 24 OD × ID combinations ranging from 3mm × 1mm (≈0.12" × 0.04") up to 19mm × 17mm (≈0.75" × 0.67"). All tubes are cut to a fixed length of 300mm (≈11.8"). The consistent 1mm wall means ID always equals OD minus 2mm — easy to calculate, easy to match.

These brass hollow tubes are well-suited for scale model framing and axle sleeves, small pneumatic or fluid lines in DIY pneumatic systems, and decorative metalwork and jewelry fabrication where a warm gold tone and easy solderability matter. The smooth drawn finish also makes them a go-to for precision brass tubing for RC vehicles and drone builds.

ℹ️ Compatibility Note: All dimensions are metric. OD sizes range from 3mm to 19mm in 0.5–1mm increments. Wall thickness is fixed at 1mm across all variants. Verify your required bore (ID) before selecting — ID = OD − 2mm.

✅ Key Features of These Brass Round Hollow Tubes

  • 🔩Consistent 1mm Wall Thickness — Every variant maintains a precise 1mm wall, so ID is always OD − 2mm. No guesswork when selecting sizes for tight-tolerance brass tubing projects.
  • 📏24 Size Options in One Listing — OD from 3mm to 19mm covers a wide range of small-diameter brass hollow tube applications, from fine model work up to light structural sleeves.
  • ⚙️Drawn Smooth Finish — The exterior surface is drawn to a consistent round profile, making these tubes suitable for sliding fits, bearing sleeves, and decorative exposed metalwork without additional finishing.
  • 🔥Solderable & Brazeable — Brass bonds readily with standard rosin-core solder, silver solder, and brazing alloys — ideal for model builders and electronics fabricators who need reliable joints on precision brass tubing.
  • 🌿Natural Corrosion Resistance — Brass resists oxidation in typical indoor and sheltered environments, making these hollow tubes a durable choice for decorative trim, craft projects, and light-duty fluid lines.
  • ✂️Easy to Cut & Machine — At 300mm (≈11.8") per tube, there's enough length to cut multiple pieces. Brass machines cleanly with a pipe cutter, fine-tooth hacksaw, or mini lathe — no special tooling required for most DIY brass tube cutting tasks.

❓ Frequently Asked Questions

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

Start with the outer diameter (OD) that fits your housing or bore, then confirm the inner diameter (ID) leaves enough wall for your load. All variants here have a 1mm wall, so ID = OD − 2mm. For example, if you need a 6mm bore, choose the 8mm OD × 6mm ID variant. Lengths are fixed at 300mm (≈11.8"); cut to size with a tube cutter or fine-tooth saw.

What load or pressure can these brass tubes handle?

Brass typically offers tensile strength in the range of 300–500 MPa depending on alloy and temper. These tubes are generally well-suited for light structural, decorative, and low-pressure fluid applications. For high-pressure hydraulic or pneumatic lines, consult a mechanical engineer and verify the specific alloy and wall rating before use.

Can I use these tubes outdoors or in humid environments?

Brass is naturally corrosion-resistant and performs well in most indoor and sheltered outdoor settings. In marine or highly acidic environments, brass can develop a patina over time. A clear lacquer or paste wax coating is generally recommended for prolonged outdoor exposure to slow oxidation.

Are these metric-sized tubes compatible with standard fittings?

Yes — all dimensions are metric (mm). They are generally compatible with metric compression fittings, metric push-fit connectors, and standard metric drill sizes. For imperial fittings, verify the OD conversion before ordering (e.g., 6mm OD ≈ 0.236").

Can I solder or braze these brass tubes?

Yes. Brass is highly solderable and brazeable. Use a rosin-core or acid-core flux appropriate for brass, and a silver solder or standard 60/40 tin-lead solder for electronics and model work. For plumbing joints, use lead-free solder in accordance with local codes.

What is the length of each tube, and can I order a custom length?

Each tube is 300mm (≈11.8") long. Custom lengths are not available through this listing. Brass cuts cleanly with a pipe cutter, hacksaw, or mini lathe, so you can trim to your required length on-site with minimal effort.

What are the most common uses for small-diameter brass hollow tubing?

Common applications include scale model framing and axle sleeves, RC vehicle and drone components, jewelry and craft projects, small fluid or air lines in pneumatic systems, electrical conduit for fine wiring, and decorative architectural trim. The warm gold tone and easy machinability make brass a versatile choice across all these uses.
