How It's Made
Cuffed Tubing Ends
For what, you may ask, does one need cuffed tubing ends? These special ends are required on certain styles of tubing in order to properly attach fittings. Tubing that is corrugated or convoluted for added flexibility requires straightening at the ends to create an area that can accept standard barbed fittings. This straightening or cuffing step typically applies to tubing made from PTFE or FEP fluoropolymer.
Cuffing at NewAge Industries is accomplished using a proprietary process involving heat and mandrels. The procedure smoothes out a few inches of corrugations or convolutions – just enough for fitting attachment – at the end of a piece of tubing. The newly created shape is then set and cooled.
Without this straightening and smoothing step, the fitting's barbs may not fit properly (push up against) the entire inside diameter of the tube. Although some tubing with thin walls may be crushed or flattened enough for a better fit with the barbs, an improper fit – and leaks – are more likely.
