Brass Round Tube 500mm — Precision Hollow Tubing for Model Making, Hobby Craft & DIY

Whether you are building a scale model, fabricating a custom bracket, repairing a plumbing fitting, or crafting a decorative piece, finding hollow brass tubing in the exact wall thickness you need can be frustrating. Generic hardware store stock rarely covers the full range of outer-to-inner diameter combinations that engineers, hobbyists, and makers actually require.

Each piece is a solid-drawn brass round tube, 500mm (≈19.7") in length, available in outer diameters from 13mm (≈1/2") to 40mm (≈1-9/16") and inner diameters from 5mm to 30mm. Wall thickness varies by variant — calculated as (OD − ID) ÷ 2 — ranging from approximately 1mm to 7mm depending on the combination selected. Sold individually (1 Pcs per order).

Typical applications include scale model making and hobby craft frames, DIY furniture leg inserts and rail joiners, light engineering spacers and bushings, and decorative metalwork projects where a clean brass finish is required. The 500mm length suits most bench-cut hobby and craft applications without excess waste.

ℹ️ Compatibility Note: These are plain, unthreaded metric round tubes. Verify your required OD × ID combination against your design drawings or existing fittings before ordering. Wall thickness = (OD − ID) ÷ 2.

✅ Key Features of These Brass Round Tubes

  • 🔩Wide Size Range — OD from 13mm to 40mm with matching inner diameters, covering thin-wall to thick-wall configurations for brass round tube hobby craft and engineering use.
  • 📏Consistent 500mm Length — Each tube is 500mm (≈19.7") long, a practical bench length for model making, DIY repairs, and custom fabrication without excessive offcuts.
  • 🟡Solid-Drawn Brass Construction — Drawn from brass alloy for a smooth exterior surface, uniform wall thickness, and clean interior bore — important for sliding fits and decorative applications.
  • ✂️Easy to Cut and Machine — Brass cuts cleanly with a pipe cutter or fine-tooth saw and machines without the work-hardening issues common with stainless steel, making it suitable for DIY brass tube cutting projects.
  • 🌧️Naturally Corrosion-Resistant — Brass resists oxidation in humid and moist environments, making it a reliable choice for indoor plumbing repairs, bathroom fixtures, and light outdoor decorative use.
  • 📐Precise OD × ID Pairing — Each variant lists both outer and inner diameter so you can calculate wall thickness and confirm fit before ordering — no guesswork for hollow brass tubing size selection.

❓ Frequently Asked Questions

How do I choose the right outer and inner diameter for my project?

Measure the shaft, rod, or opening your tube needs to fit over or inside. The inner diameter (ID) should clear your insert with a small tolerance — typically 0.1–0.5mm of play. The outer diameter (OD) determines the tube's visible profile and wall thickness. Wall thickness = (OD − ID) ÷ 2. For example, a 20mm OD × 10mm ID tube has a 5mm wall. For inch reference: 25mm ≈ 1", 19mm ≈ 3/4".

What wall thickness should I choose for structural or load-bearing use?

For decorative or lightweight hobby applications, thinner walls (typically 1–3mm) are generally sufficient. For structural or load-bearing use, a thicker wall — typically 4mm or more — provides greater rigidity and resistance to bending. Brass tubing is generally suited to moderate loads; for heavy structural applications, consult a qualified engineer.

Is brass tubing suitable for outdoor or humid environments?

Brass is naturally corrosion-resistant and performs well in moist or humid indoor conditions. Outdoors, it will develop a natural patina over time. For prolonged outdoor exposure, applying a clear lacquer or metal sealant is generally recommended to maintain the original appearance and slow patina development.

What fittings or connectors are compatible with these tubes?

These are plain, unthreaded round tubes. They are generally compatible with standard metric compression fittings, push-fit connectors, and slip-fit couplings sized to match the OD. For threaded connections, a separate threaded fitting or coupling would be required. Contact us to confirm compatibility with your specific fitting or application.

Can I cut this brass tube to a shorter length?

Yes. Brass cuts cleanly with a pipe cutter, hacksaw, or fine-tooth metal saw. A pipe cutter generally produces the cleanest, squarest cut with minimal burring. Deburr the cut end with a file or deburring tool before use to avoid sharp edges and ensure a clean fit.

Which size is best for scale model making or hobby craft?

For scale model making, sizes in the 13–20mm OD range with thin walls (1–3mm) are most commonly used. For structural hobby frames or larger craft builds, 22–32mm OD tubes with medium walls are generally preferred. Select the OD × ID combination that matches your design drawings or the rod/shaft you are fitting around.

Is this sold as a single piece or in a multi-pack?

Each order is for 1 piece (1 Pcs) of brass round tube, 500mm (≈19.7") in length. If you need multiple pieces, simply increase the quantity at checkout. Select your required OD × ID combination from the variant options above before adding to cart.
