Whichever fitting is used, deburring the freshly cut tube is a crucial step. It must be known that when a leak occurs at a connection, the cause is usually due to poor deburring.

The purpose of this operation is to chamfer the end of the tube to remove all residues (chips and other plastic dusts) that could affect the sealing of the connector... and recalibrate the end of the tube that could s crush slightly when cutting, and must find a perfect shape to ensure tightness.
This work is done with a manual chamfer calibrator or mounted on a screwdriver. This second version is the most practical: no need to force, the blade gently cuts the edges of the tube without deforming it.
When the tube has been cleaned, chamfered and calibrated, it fits exactly into the fitting and thus ensures the tightness of the system, and its durability.

Cut net the multilayer pipe

To obtain a clear cut of the tube and its different layers, use a special pliers.

chamfer calibrator

Insert the tube into the chamfer calibrator. Without forcing, pull out the plastic chips by operating the handle.

deburr the multilayer pipe

Easier, mount the chamfer on a screwdriver, insert the tube and deburr at a fast speed without pressing too hard.

If you force too much on the tube, it deforms and you have to start again... Below, a perfectly chamfered tube.
