Micro Brass Tube 3mm OD — Precision Hollow Pipe for Scale Modeling & Craft Builds

Scale modelers, RC builders, and precision craft enthusiasts know the frustration of finding metal tubing that is dimensionally consistent, easy to cut, and actually solderable without warping. Whether you are scratch-building a diorama structure, fabricating push-rod guides for an RC vehicle, or adding fine metalwork to a model kit, having reliable micro brass tube on hand makes the difference between a clean build and a compromised one.

Each piece is a hollow brass tube with a 3mm outer diameter (≈0.118") and a length of 200mm (≈7.9"). Available in quantities of 1, 5, or 10 pieces per order, so you can stock up for ongoing projects or grab a single piece for a quick repair. The brass alloy construction provides a smooth, consistent bore and a uniform wall thickness throughout the length of each tube.

Typical use cases include structural framing in 1:35 and 1:48 scale military dioramas, antenna and push-rod sleeves in 1/10 RC cars and aircraft, and decorative metalwork in architectural models and steampunk craft projects — all applications where a precise 3mm OD hollow brass pipe is the go-to material choice.

ℹ️ Compatibility Note: Outer diameter is 3mm. Inner diameter varies by wall thickness — contact us to confirm bore size before planning press-fit or threaded assemblies. Compatible with standard metric 3mm collets, fittings, and M3 threading dies.

✅ Key Features of These Micro Brass Hollow Tubes

  • 📏Consistent 3mm OD Tolerance — Uniform outer diameter across the full 200mm length ensures reliable fit in collets, fittings, and model assemblies without hand-fitting or shimming.
  • ✂️Easy to Cut & Shape — Brass cuts cleanly with a fine-tooth saw, rotary tool, or dedicated tube cutter, making it ideal for scratch-building scale model structures where custom lengths are needed.
  • 🔥Solderable with Standard Tools — Joins readily with rosin-core solder and a basic soldering iron, so you can build multi-piece assemblies or repair existing metalwork without specialized equipment.
  • 🛡️Naturally Corrosion-Resistant — Brass resists oxidation better than mild steel, making these hollow brass pipes suitable for display models and indoor craft projects that need to hold their appearance over time.
  • 📦Flexible Quantity Options — Order 1, 5, or 10 pieces to match your project scope. The 10-piece pack is especially useful for RC builders and modelers who work through multiple tubes per build.
  • ⚙️Versatile Precision Metal Stock — Works as push-rod guides, antenna mounts, axle sleeves, structural tubing in architectural models, and decorative elements in steampunk or industrial-style craft builds.

❓ Frequently Asked Questions

How do I choose the right length for my project?

This tube is 200mm (approximately 7.9 inches) long. For most scale modeling applications, a single piece is sufficient for structural framing or axle work. If your project requires longer runs, you can generally join multiple pieces end-to-end using a slightly smaller inner rod as a sleeve. Measure your required span first and round up to the nearest 200mm increment.

How strong is a 3mm brass tube under load?

Brass tubing at 3mm OD is typically used for light structural and decorative applications — scale model framing, RC push-rod guides, and antenna mounts. It is not rated for heavy structural loads. For load-bearing applications, wall thickness and alloy grade are critical factors. Contact us to confirm specifications before ordering for structural use.

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

Brass is naturally more corrosion-resistant than mild steel and generally performs well in moderate humidity. Prolonged exposure to moisture or salt air can cause surface tarnishing over time. For outdoor display models or garden-scale projects, applying a clear lacquer or protective coating is recommended to maintain the brass finish.

What fittings or thread standards are compatible with this tube?

This is a plain hollow tube with no pre-cut threads. The 3mm OD is compatible with standard metric fittings and collets designed for 3mm stock. If you need threaded ends, the tube can typically be threaded with an M3 die. Contact us to confirm the inner diameter before planning threaded or press-fit assemblies.

Can I cut or solder this brass tube at home?

Yes. Brass is one of the most workable metals for hobbyists. It cuts cleanly with a fine-tooth saw, rotary tool, or dedicated tube cutter, and solders easily with standard rosin-core solder and a soldering iron. It also accepts CA (cyanoacrylate) adhesive well for non-structural joins in scale model builds.

Is this tube suitable for RC car axles or antenna mounts?

Yes, 3mm OD brass tubing is commonly used for lightweight RC car axle sleeves, antenna mounts, and push-rod guides. It is generally stiff enough for these applications while remaining easy to cut and shape. For high-torque axle applications, verify the inner diameter matches your shaft size before ordering.

What is the inner diameter of this tube?

The outer diameter is 3mm. Inner diameter varies by wall thickness and is not printed on the packaging. Please contact us to confirm the exact inner diameter for your specific application — especially if you need a precise bore fit for a shaft or rod.
