This jig makes pressing HPA QD plug for 6 mm macroline even easier.
Clamp the 6 mm low-pressure HPA hose into the jig using a vise. Leave only as long a part of the hose protruding as the length of the crimping mandrel on the QD coupling. Then simply press the QD coupling in.
Ideally, the coupler should be clamped in the accu drill and inserted into the hose at slow speed. Caution, do not heat the hose in any way before application!
