SKU CH-R6Q0-K4SD7

Three seamless 6063 aluminium tubes, 18 mm outer diameter by 14 mm inner diameter and 300 mm long, suit custom fabrication and fluid-transfer projects

  • 6063 aluminium alloy delivers high strength and corrosion resistance for durable builds
  • Seamless construction provides a smooth interior bore for unrestricted flow in precision applications
  • 18 mm outer and 14 mm inner diameters suit custom fabrication and DIY projects
  • 300 mm length per tube offers ample material for cutting, drilling or welding
  • Three-piece pack supplies enough tubing for multiple assemblies or spare stock

6063 Aluminium Tubing 300 mm Length

These three 6063 aluminium tubes measure 300 mm long with an 18 mm outer diameter and a 14 mm inner diameter. The seamless construction gives a smooth interior for fluid flow or precision fits. They suit custom fabrication in automotive, marine, aerospace and general workshop projects. The alloy provides high strength, corrosion resistance and good weldability for durable builds.

Easy to Cut Drill and Weld

The material can be cut and drilled with standard workshop tools and welded using appropriate equipment. The seamless extruded finish means no internal ridge to snag fittings or restrict flow. A common issue is underestimating the force needed to bend the tube without kinking; use a proper bender or mandrel for tight radii. Always deburr the cut ends before assembly to prevent leaks or stress concentrations.

Check Project Dimensions and Alloy Compatibility

Verify that the 18 mm outer and 14 mm inner diameters match your design requirements for flow rate, structural load or fitting compatibility. Confirm that 6063 aluminium is suitable for the intended environment, especially if the assembly will contact dissimilar metals or specific chemicals. Ensure you have the necessary tooling for cutting, deburring and any planned welding or bending operations before ordering.

Questions about this item

How can I verify the 6063 aluminum tubing meets the 18mm outer diameter and 14mm inner diameter after cutting?

Measure the tube ends with a digital caliper; the outer diameter should read 18mm and the inner diameter 14mm, confirming the seamless 6063 alloy extrusion is within spec.

What comes in the package and do I need any extra fittings or tools?

The box contains three 300mm seamless 6063 aluminum round tubes; no fittings, connectors or cutting tools are included, so source those separately for your fabrication project.

Should I choose the 18mm OD × 14mm ID × 300mm length or a different size for a custom air intake build?

This listing only offers the 18mm outer diameter, 14mm inner diameter, 300mm length in a three-piece pack; if your design requires different dimensions you will need another listing.
