- 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.
