CRP1096 PEX Clamp Tool Kit: Wow this tool worked perfectly and came with plenty of clamps to install. Twenty 1/2″ and ten 3/4″. I used one 1/2″ clamp per connection which was perfectly adequate with the barbed brass adapters I sweated on. No leaks and do not expect any. See pic.

I bought this to crimp Molex SL pins and sockets.
It performs well on the tiny pieces.
You have to make sure that the tool is aligned to just crimp the part that grabs the wire or the part that grabs the insulation before crimping down.
View both sides before crimping!
Insulation diameter variance and make crimping more difficult to insert the pins into the connector.
Applying more pressure than necessary will distort the connector and make it difficult to insert. Check that the pin or socket is still straight after crimping and adjust if necessary.
Tool is well made and not sloppy.

Very good crimper for the money. Very happy. I prefer this 6 side version over the 4 for most applications. This crimper is perfect for the listed wire sizes.
For those saying it is too small I can only assume you are either NOT using ferrules (as in trying to use it as a standard wire crimper which will NOT work) or you have insanely large ferrules.

Let me be clear – this is for the little ferrules that go on the end of a wire to insure better connections in screw terminals – typically fond in control boxes or panels (and sometimes in breaker boxes when stranded is used)
This is a great tool and does exactly what it was designed to do – crimp ferrules – no frills.
