iCrimp Weather Pack Crimper Tools for Delphi APTIV Packard Weather Pack Terminals Metri-Pack Connectors for Sealed Terminals

I've been using these electrical crimp pliers regularly for wiring projects, and I have to say, they’re an essential tool for anyone working with connectors. A good pair makes all the difference between a solid, professional connection and a frustrating, unreliable one.Build Quality:The pliers I use have a sturdy, all-metal construction with ergonomic, rubberized grips. They feel solid in the hand and provide enough leverage to crimp firmly without much effort. The ratcheting mechanism ensures consistent pressure, which helps avoid over- or under-crimping.Performance:They handle a variety of connector sizes, especially insulated terminals, non-insulated connectors, and sometimes even ferrules. The color-coded dies or indicators are very helpful for matching the correct wire gauge. Crimps come out tight and secure every time, with minimal deformation of the connector.Ease of Use:After a little practice, the process is quick and intuitive. Insert the terminal and wire, squeeze until the ratchet releases, and you’re done. The tool locks in place until the crimp is complete, which helps prevent half-done crimps.Downsides:Some cheaper models may have misaligned jaws or inconsistent ratcheting, so it's worth investing a bit more for a reliable brand. Also, while versatile, one crimper may not cover every type of terminal—so a multi-tool or interchangeable die set can be useful if you're working with a variety of connectors.Overall:Electrical crimp pliers are a must-have for clean, strong, and professional wire terminations. A good-quality pair saves time, prevents electrical issues, and makes your work look top-notch. Highly recommended for DIYers, auto techs, and electricians alike.

Accurate crimping of Weatherpack terminals. The ratcheting mechanism makes the job easier and it also prevents over-crimping of the terminal itself. The tool is a bit heavier than most, but it is well constructed, high quality, has well padded handles, and the ability to not to loose it’s grip on the terminal you are working on make it worth while. I own several icrimp tools for other applications (PEX clamps, for example) and prefer them over some higher priced crimpers that don’t have the capabilities of this tool. I’ve used it on 30+ terminals so far and would give it an excellent rating.

I had to look up the correct way to use this crimper. It would have been nice for there to be some instructions with it. But after finding out how to properly use it, it works well.

I used this crimping tool to make jumper wires from 22 AWG wires. The tool worked effectively, and its price is also reasonable.

These crimpers arrived today and I went out and did some test crimps. I meant to use these on bare regular crimp terminals as well as Molex Style DELPHI AMP TYCO Terminals. It does the bare regular crimp terminals reasonably well but you have to get used to it and how it works. With bare regular crimp terminals they have a split and that split needs to be dealt with properly if you are going to get a very tight crimp.The crimp section that is meant to fold the open Molex Style properly also does the same thing to the regular crimp terminals if you take the time and position the split the proper way.I wondered if this would work out, and it does. I have to use all the slots on this crimper except the smallest one but it works. The bare terminals I'm doing are smaller awg 18 - 22 size. The terminals are ELECALL IT-420 420pcs 18 in 1 Crimp Terminals bought here on amazon.I also have some Molex Style terminals that are from a relay panel that holds 5 Bosch 24v relays that plug in from the top. The Molex Style terminals slip in from the bottom and are held via small tabs that are bent out.This crimper worked on those but did have some problems with the wings on the open style terminal. I had to work it slowly until I could get those wings to behave and bend over in the center. Same thing for the outer part that grips the insulation, it worked but took some technique before it was properly crimped.I am going to finish these off with Eventronic 3:1 Heat Shrink Tubing bought here on amazon, the type with glue inside so it seals and once cooled holds very well.I do not know what type of terminals this crimper would "just work" on as in, grab, crimp, done. It does what I hoped it would do, crimp regular bare terminals, but with some careful "technique" applied.The wiring job I bought all this for is a 2006 Enco 14x40 industrial lathe. I am rewiring the entire thing from 3ph to use a VFD drive. The on, start, stop, forward and reverse, E-Stop and safety interlocks are all going to work as it did before I removed the entire electrical panel with old relays and transformer and replaced it all with the VFD drive and 5 Bosch 24v relays. This is the type of job that will be done once and has to be done in such a way so it will be reliable and last, perhaps longer then me.~

This tool is well made and solid. It gives enough "feel" to hold the item to be crimped with one hand without damaging it. The best thing is that it is thin enough to see when you are crimping only the part you intend. Of course that means you crimp twice: once for the conductor and once for the insulator. I don't waste nearly so many badly crimped pins since buying this tool. I tried two others first, this is the best.

Spring grip and light weight. Great price!
