Unique-Bargains Copper Pipe Assortment 2-7mm OD 0.2mm Wall 300mm Pack of 6

SKU CH-SE9N-XHQAZ

Assorted seamless copper tubes in six sizes from 2 mm to 7 mm OD with 0.2 mm walls, 300 mm long, for precision DIY and model work

  • Precision-ready seamless tubing for clean fluid paths
  • Six diameters from 2 mm to 7 mm OD in one pack
  • Passivated copper resists oxidation and corrosion
  • 300 mm straight lengths suit modelling and plumbing
  • Thin 0.2 mm wall allows easy forming and punching

Copper tube assortment for precision work

This pack contains six seamless copper tubes ranging from 2 mm to 7 mm outer diameter with a uniform 0.2 mm wall thickness. Each piece measures 300 mm in length and features a passivation finish for oxidation and corrosion resistance. The smooth interior and exterior surfaces suit precision applications in modelling, crafts and light engineering.

Ready to cut and form for custom builds

The tubes arrive straight and can be punched, bent or machined with appropriate tooling to match specific project requirements. Their thin wall profile keeps weight low while maintaining structural integrity for frames, decorative elements or fluid pathways. No additional fittings or treatments are included, so builders supply their own joining methods and finishing steps.

Six diameters in one pack reduce sourcing time

Having 2 mm through 7 mm sizes in a single package lets hobbyists and prototypers test fitment without ordering multiple SKUs. The consistent 300 mm length provides a common reference dimension for layout planning across all sizes. Users needing longer runs, thicker walls or pre-flared ends will need separate stock.

Questions about this item

How thin is the 0.2 mm wall on the 7 mm tube before it buckles under sustained bending?

The 0.2 mm wall thickness on the 7 mm OD tube is the smallest cross-section in the assortment, so it reaches its bend-radius limit first under sustained forming pressure.

Does the copper tube heat up or require power when left in a fixed installation all day?

The copper tube is a passive component with no electrical or moving parts, so it generates no heat, noise or power draw during continuous use.

What tools must I already own to cut, flare or join these seamless copper tubes?

You need a tubing cutter or fine-tooth saw for the 300 mm lengths, a flaring tool sized for 2–7 mm OD, and a torch with silver-solder or compression fittings rated for thin-wall copper.
