Brass Round Tube with 1.5mm Wall — Precision Hollow Tubing for DIY, Modeling & Fabrication

Whether you're building a scale model, fabricating a custom bracket, or need a reliable spacer for a mechanical assembly, finding a brass round tube in the exact size you need shouldn't be a project in itself. Machinists, hobbyists, and makers working on precision DIY builds often struggle with tubes that are too thick-walled, too short, or simply not available in the right outer diameter — this listing solves that with 15 metric sizes in one place.

Each tube is made from solid brass alloy with a uniform 1.5mm wall thickness. Outer diameters range from 5mm (≈3/16") to 19mm (≈3/4"), with inner diameters running 3mm smaller than the OD across all variants (e.g., OD 8mm × ID 5mm). Every piece is cut to a standard length of 300mm (≈11.8"), giving you enough material to trim to your exact requirement. Select your OD × ID combination from the variant dropdown above.

These brass hollow round tubes are a go-to choice for model railway and RC vehicle builds requiring precise metal tubing, custom furniture and lamp fabrication where a decorative metal tube is needed, and plumbing prototypes and fluid-line mockups that call for a corrosion-resistant, solderable tube in metric sizing.

ℹ️ Metric sizing: All dimensions follow standard metric specifications. OD ranges from 5mm to 19mm; wall thickness is fixed at 1.5mm across all variants. ID = OD − 3mm. Verify your required bore and outer fit before ordering.

✅ Key Features of These Brass Round Hollow Tubes

  • 🔩Consistent 1.5mm Wall Thickness — Uniform wall across all 15 size variants ensures predictable strength and a reliable ID-to-OD relationship for precision fitting work.
  • 📏Wide Size Range in One Listing — OD from 5mm (≈3/16") to 19mm (≈3/4") lets you pick the exact metric tube size for your project without ordering from multiple suppliers.
  • ✂️300mm (≈11.8") Standard Length — Long enough for most applications and easy to cut down with a pipe cutter or fine-tooth hacksaw to your required dimension.
  • 🔥Solderable & Machinable Brass Alloy — Brass hollow round tubing machines cleanly, accepts solder and brazing, and can be drilled or tapped — ideal for model engineering and custom fabrication.
  • 🌿Natural Corrosion Resistance — Brass resists oxidation better than plain steel, making these tubes suitable for moderately humid environments and decorative indoor-outdoor applications.
  • ⚙️Standard Metric Compatibility — Sized to metric standards, these tubes fit standard metric couplings, bushings, and fittings used in DIY plumbing prototypes and mechanical assemblies.
⚠️ Confirm your size before ordering: Each variant is labeled OD × ID (e.g., 10mm × 7mm). The wall thickness is always 1.5mm. If you need a specific bore size, select the variant where ID matches your requirement.

❓ Frequently Asked Questions

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

Measure the hole or bore you need to fit the tube into — that determines your outer diameter (OD). This tube is 300mm (approximately 11.8") long. If you need a shorter piece, it can typically be cut with a pipe cutter or fine-tooth saw. Always allow a small tolerance (generally 0.1–0.2mm) when fitting into a drilled hole.

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

All variants in this listing have a uniform 1.5mm wall thickness. This provides a solid balance between weight and structural rigidity for most hobby, craft, and light mechanical applications. For heavy load-bearing use, a thicker-walled tube is generally recommended.

Can this brass tube be used outdoors or in humid environments?

Brass has naturally good corrosion resistance compared to plain steel, making it suitable for moderately humid or indoor-outdoor environments. For prolonged outdoor exposure or direct water contact, applying a clear lacquer or sealant is generally recommended to maintain the finish.

Is this tube compatible with standard metric fittings?

Yes — all dimensions follow standard metric sizing, making these tubes compatible with metric couplings, bushings, and fittings in most cases. Always verify the ID of your fitting against the OD listed in the variant you select.

Can I solder, braze, or machine this brass tube?

Brass is one of the most machinable and solderable metals available. These tubes can typically be cut, drilled, tapped, soldered, or brazed using standard tools and techniques. They are well-suited for model engineering, plumbing prototypes, and custom fabrication work.

How do I select the correct size variant?

Each variant is listed as OD × ID (e.g., 8mm × 5mm). The OD is the outer diameter — the overall tube size. The ID is the inner bore. All variants share a 1.5mm wall thickness, so ID = OD − 3mm. Choose based on the bore size you need to pass through the tube, or the outer dimension needed to fit into a housing.

What finish does this brass tube have?

These tubes typically have a natural mill finish — a smooth, slightly golden brass surface without additional plating or coating. The finish is consistent and suitable for decorative, functional, or further-processed applications.
