Wire crimping tool?

Post by friedman » Wed May 16, 2018 8:52 am

I have one from HF but it really does not crimp the connectors on tight enough. Any recommendations on a reasonably priced wire crimper?
Use is for the automotive type ends, red, blue and yellow sizes.

Probably not the cheapest, but cheap isn't always better.

Thanks, but I use insulated terminals....yes the kind everyone says not to use but most of us do anyway.

I use a similar tool for crimping insulated connectors. Just be exact on how and where you crimp and they work fine. Don't by a cheap tool.

OK, I'll go to HD and see if they have one for insulated terminals. The one I have is some complex thing that has linkages and pivoting arms and stuff.

I use it on insulated all the time.
The center section not the inner part with the serious chrunchy bit...

Below are links to 2 crimpers designed for the colored insulated wire terminals. The one from aircraft Spruce is easier to compress the crimp because the handle is longer. The cutter being in the front sometimes makes it difficult to clear other wires.

The one on ebay is shorter and crimps slightly more round. It works well to open a crimp to remove a terminal. Carefully crimping an existing crimp 90 degrees to the original crimp loosens it enough to pull the terminal off. Also because the tool is smaller its handy in tight spaces.

I was taught the sta-kon type tool mentioned from HD was designed for bare metal terminals that had a separate plastic sleeve that slid over it for insulation. These terminals were pretty much phased out in the 1960's In many cases using a sta-kon crimper on insulated terminals damages terminals insulation. I realize it is marketed by some suppliers with insulated terminals but I would shy away from its use.

Either of the crimpers I show links for are designed for insulated terminals and work satisfactory

--I bought one of these years ago, and I'm totally pleased with the quality and reliability of the crimps for both insulated and non-insulated connectors, particularly common 14, 12 and 10 gauge connectors. It takes the guesswork out. Sometimes a little difficult in tight spaces.

I use the Dorman one that Jim linked to. It has interchangeable jaws to handle a wide variety of connectors and a ratcheting mechanism for easier more consistent closing. Got it originally for telephone and Ethernet wiring but use it in the cars when space allows. No tool will compensate for low quality and mis-sized connectors.

I agree nice tool in that it does not allow partial crimps. One has to compress fully for the jaw to open. Also it makes the wire crimp and the insulation crimp with one action where the ones I posted usually takes 3 separate crimping actions. I feel the disadvantage of this tool is it is more tedious to operate. In some work areas like upside down under a dash it could be a problem. So I actually have about 5 different style crimpers sort of like other tools at one time one will be better suited than another.
The cost verses use is always a factor and sometimes over rides quality. Its important to pull on the terminal forcefully after a crimp to be sure the crimp is solid and will not come off. The quality of the terminal is also important. There are inexpensive terminals that regardless of the crimper quality do not crimp tightly to the wire. Also any damage to the insulation usually indicates either improper tool or use of tool.
