Brass Round Tube — Precision Hollow Tubing, OD 3mm to 50mm, 500mm Length
Whether you're a hobbyist building scale models, a maker fabricating custom frames, or a tradesperson needing a reliable spacer or sleeve, finding hollow brass round tube in the exact diameter you need — without ordering a full industrial run — is frustrating. These brass round tubes are stocked in 42 OD sizes from 3mm (≈1/8") up to 50mm (≈2"), all with a consistent 1mm wall thickness, so you can pick the precise fit your project demands.
Each piece is a single hollow round tube, 500mm (≈19.7") long, turned from brass with a uniform 1mm wall. The outer diameter (OD) and inner diameter (ID) are clearly paired in every variant — for example, the 10mm OD variant has an 8mm ID, and the 25mm OD variant has a 23mm ID. The consistent 2mm OD-to-ID difference across all sizes makes nesting tubes straightforward for telescoping assemblies.
Typical applications include DIY furniture legs and rail inserts, RC vehicle and drone frame tubing, scale model structural members, fluid and air line sleeves, electrical conduit liners, and decorative architectural accents — anywhere a clean, machinable, corrosion-resistant hollow brass round tube is called for.
Sizing note: OD and ID are listed together in each variant (e.g., "10mm x 8mm" = 10mm OD, 8mm ID, 1mm wall). Confirm your required bore or sleeve diameter before selecting. All pieces are 500mm (≈19.7") long and can be cut to length.
✅ Key Features of These Brass Round Tubes
- 42 OD Sizes in One Listing — Choose from OD 3mm (≈1/8") to 50mm (≈2") in incremental steps, all with a 1mm wall, so you get the exact hollow brass round tube diameter your project needs without custom cutting fees.
- Consistent 1mm Wall Thickness — A uniform wall across all sizes means predictable rigidity, easy ID calculation (OD − 2mm), and straightforward nesting for telescoping brass tube assemblies.
- Machinable & Solderable Brass — Brass cuts cleanly with a pipe cutter or fine-tooth saw, drills and taps without chipping, and accepts solder and brazing alloys readily — ideal for precision fabrication and model making.
- Natural Corrosion Resistance — Brass resists oxidation in typical indoor and moderately humid environments, making these tubes suitable for decorative hardware, fluid sleeves, and light outdoor applications without additional coating.
- 500mm Stock Length — At 500mm (≈19.7"), each tube provides a practical working length that covers most DIY and hobby cuts while remaining easy to ship and handle.
- Versatile Cross-Application Use — From RC frame tubing and scale model structural members to furniture rail inserts and electrical conduit liners, these hollow brass round tubes serve a wide range of structural and decorative roles.

❓ Frequently Asked Questions
How do I choose the right OD and length for my project?
Measure the opening or bore you need to fit the tube into — that determines your required OD. For length, 500mm (≈19.7") is a standard stock length that can be cut down with a pipe cutter or fine-tooth saw. When in doubt, size up on OD and trim to fit. All OD/ID pairs are listed in the variant selector so you can confirm the bore before ordering.
What load or pressure can these brass tubes handle?
Brass tubing with a 1mm wall is generally suited for light-duty structural, decorative, and low-pressure fluid applications. For high-pressure hydraulic or pneumatic lines, a thicker wall is typically recommended. Contact us to confirm suitability for your specific load or pressure requirements.
Can these tubes be used outdoors or in humid environments?
Brass is naturally corrosion-resistant and performs well in most indoor and moderately humid outdoor environments. It will develop a patina over time when exposed to the elements. For marine or highly corrosive environments, additional sealing or a protective coating is generally advisable.
Are these tubes compatible with standard brass fittings and connectors?
These tubes are sized by OD (outer diameter), which is the standard reference for most compression fittings and push-fit connectors. Always verify the fitting's bore matches the tube OD you select. Thread compatibility depends on the fitting type — confirm the thread standard (BSP, NPT, or metric) with your fitting supplier before ordering.
Can I solder, braze, cut, or machine these brass tubes?
Yes. Brass is one of the most machinable and solderable metals available. These hollow brass round tubes can typically be cut with a pipe cutter or fine-tooth hacksaw, drilled, tapped, soldered, or brazed with standard tooling. Deburr cut ends with a file or deburring tool for a clean finish.
Which size should I choose for model making or hobby projects?
For scale model making, RC vehicle frames, and hobby fabrication, smaller OD sizes (3mm–10mm) are most commonly used. The 1mm wall thickness provides a good balance of rigidity and light weight at these scales. If you need tubes to nest inside one another for a telescoping assembly, select sizes where one OD closely matches the next ID — the consistent 2mm OD-to-ID difference across this range makes that straightforward.
What is the inner diameter (ID) for each size?
Because the wall thickness is consistently 1mm, the ID is always OD minus 2mm. For example, the 10mm OD tube has an 8mm ID (≈0.31"), and the 25mm OD tube has a 23mm ID (≈0.91"). All OD/ID combinations are listed in the variant selector above for easy reference.
