Tool for crimping the HPA QD crimp coupling for 6mm tubing. This tool makes crimping the HPA QD crimp coupling for 6mm tubing much easier.

Procedure. Allow only as long a section of tubing to protrude as the length of the crimping mandrel on the QD coupling. Then we simply crimp the QD coupling on. Ideally, the coupling is clamped in an accutane drill and inserted into the tubing at a slow speed. Caution, do not heat the tubing in any way before application!
