Brass Round Tube Pipe — Precision Hollow Tubing for DIY, Modeling & Fabrication

Whether you're building a scale model, repairing a plumbing line, or fabricating a custom bracket, finding brass round tube pipe in the exact outer diameter and wall thickness you need can be frustrating. Generic hardware store stock rarely covers the full metric range — and ordering the wrong wall thickness wastes both time and money. These brass hollow round tubes are available in outer diameters from 6mm (≈1/4") to 40mm (≈1-9/16") with wall thicknesses of 0.2mm, 0.5mm, 1mm, 1.5mm, and 2mm, giving hobbyists, makers, and tradespeople precise control over bore size and wall rigidity.

Each piece is a single 300mm (≈11.8") length of seamless-style brass round tube. The format is OD × Wall × Length — for example, "10 × 1 × 300mm" means a 10mm outer diameter, 1mm wall thickness, and 300mm length, yielding an inner diameter of approximately 8mm (≈0.31"). Sizes span from ultra-thin 0.2mm walls for lightweight decorative work up to robust 2mm walls for structural or pressure-bearing applications. Over 130 size combinations are available as individual variants.

Typical use cases include scale model aircraft and RC vehicle frames where lightweight brass round tube for model making is essential, DIY plumbing and pneumatic prototyping where metric brass pipe tubing with precise OD is required, and craft or jewelry projects where small-diameter brass hollow tube adds a polished metallic accent. The 300mm cut length fits most bench vises and pipe cutters without additional trimming.

ℹ️ Size Compatibility Note: Inner diameter = OD − (2 × Wall Thickness). Example: 12mm OD × 1mm wall = 10mm ID (≈0.39"). Confirm your required bore size before selecting a variant. Metric sizes — verify against your fitting standard.

✅ Key Features of These Brass Round Tube Pipes

  • 📐Wide Size Range — OD from 6mm (≈1/4") to 40mm (≈1-9/16") with four wall thickness options (0.2 / 0.5 / 1 / 1.5 / 2mm), covering the most common metric brass hollow tube sizes in one listing.
  • 🔩Consistent Wall Thickness — Uniform wall construction throughout the 300mm length ensures predictable inner diameter and even material distribution, important for press-fit and soldered joints.
  • 🛡️Natural Corrosion Resistance — Brass alloy construction resists oxidation and moisture, making these tubes suitable for indoor plumbing prototypes, decorative outdoor fixtures, and humid workshop environments.
  • ✂️Machinable & Solderable — Brass cuts cleanly with a standard pipe cutter or fine-tooth saw and accepts common flux-core solder, making it straightforward to trim, join, or thread for custom brass tube fabrication projects.
  • 📏300mm Ready-to-Use Length — At 300mm (≈11.8"), each tube fits most bench vises and is a practical starting length for scale model brass tubing, jewelry mandrels, and short-run fabrication without excess waste.
  • 🎯Single-Piece Ordering Flexibility — Buy exactly the size you need without committing to bulk packs. Ideal for prototyping, repair work, or mixed-size projects where only one or two pieces of a specific OD and wall are required.

❓ Frequently Asked Questions

How do I choose the right outer diameter and wall thickness?

Measure the opening or shaft your tube needs to fit over or inside. The outer diameter (OD) is the outside measurement; the wall thickness determines how much material surrounds the hollow bore. Inner diameter = OD − (2 × Wall). For example, a 10mm OD with 1mm wall gives an ID of approximately 8mm (≈0.31"). Thicker walls generally provide more rigidity. If you need a tube to slide over a 6mm rod, choose an OD of 7mm or larger with an appropriate wall.

What is the inner diameter (ID) for a given size?

Use the formula: ID = OD − (2 × Wall Thickness). Examples:

  • 8mm OD × 0.5mm wall → ID ≈ 7mm (≈0.28")
  • 12mm OD × 1mm wall → ID ≈ 10mm (≈0.39")
  • 20mm OD × 2mm wall → ID ≈ 16mm (≈0.63")

Confirm your required bore before ordering. If you need a specific ID, contact us and we can help identify the right variant.

How strong is brass tubing compared to copper or aluminum?

Brass is generally harder and stronger than pure copper and softer than steel. It typically offers good tensile strength for light structural, decorative, and fluid-carrying applications. Thicker walls (1.5mm–2mm) increase load-bearing capacity significantly. For heavy structural loads or pressure systems, consult an engineer and verify the specific alloy grade.

Can brass tube be used outdoors or in humid environments?

Brass has naturally good corrosion resistance and is commonly used in marine hardware, outdoor plumbing fittings, and decorative exterior fixtures. In most cases it will develop a golden-brown patina over time rather than rust. For harsh saltwater or chemical environments, a clear lacquer or protective coating is generally recommended to preserve appearance.

Is this tubing compatible with standard plumbing or pneumatic fittings?

These tubes use metric outer diameter sizing. Compatibility with NPT, BSP, or compression fittings depends on the specific fitting's bore and seating design. Always verify the OD and wall thickness against your fitting's specification before use. Contact us to confirm compatibility if you are unsure — we're happy to help match the right size.

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

Yes. Brass is generally easy to work with:

  • Cutting: Use a sharp pipe cutter or fine-tooth hacksaw. Thin-wall variants (0.2mm) require extra care to avoid deformation.
  • Soldering: Standard flux-core solder and brass-compatible flux work well for joining pieces.
  • Machining: Brass machines cleanly on a lathe or mill with standard HSS or carbide tooling.
What are the most common uses for this brass tube?

Common applications include scale model aircraft and RC vehicle frames, DIY plumbing and pneumatic prototyping, jewelry and craft projects, decorative railings and furniture accents, electrical conduit sleeves, and custom bracket fabrication. The 300mm length is convenient for most bench-top projects without requiring additional trimming.

How do I decide between 0.5mm, 1mm, 1.5mm, and 2mm wall thickness?

As a general guide: 0.2mm walls are for lightweight decorative and modeling work where weight matters most. 0.5mm walls suit craft projects and light-duty structural use. 1mm walls are a versatile choice for most DIY and prototyping applications. 1.5mm–2mm walls are appropriate for higher-stress applications, thicker joints, or when you need a more rigid tube that resists bending.
