The length of swage for each tube are as follows:

  • 25.4mm-51mm

  • 35.0mm-31.0mm
  • 50.8mm-46.8mm
  • 60.3mm-56.3mm

A 'Swaged' joint creates an OD that will fit our supplied tube 'Plain' and adds a nominal increase in the length of 2.5mm - Example a tube 100cm long (1000mm) with 'Swage Ends' at each end will result in a final length of 100½cm (1005mm). We can send a small sample of a swaged tube if you wish to check the OD of the swaged tube with material not sourced from ourselves.

A 'Flattened' joint creates a nominal loss in the length of 5mm - Example a tube 100cm long (1000mm) with 'Flattened Ends' at each end will result in a final length of 99cm (990mm). Flattened End for 60.3mm is not available.

Clamps and Clips and Fasteners are also available.
