    Easy to use They fit/clean nice versa a wire brush

  2. Edwin E Freeman

    Exactly what I needed Had an outside air compressor unit for our main floor decide to pop the plug off from the compressor itself. Noticed the male pin felt very rough and figured it was getting warm and was unsafe. The largest of these tools fit it perfectly, just a few times on and off and I had a good connection. Must have for plugs that are sometimes exposed to weather.

    Outstanding Product I use this for my plowing harness among other things. This product saves me from having to replace harnesses. Easy to use. Does a great job. I highly recommend.


    Great Product great for cleaning electrical terminals

  5. Gary A. Williams

    Thumbs up These worked excellent for cleaning my 4 and 7 pin trailer connections.

  6. TC Guy

    Buy This! Where have these tools been all my life? I’d been messing around with the harness on my truck and the boat trailer for a week…emery cloth rolled up, etc etc…y’all know the drill. Once I received these in 5 minutes I had good strong lights! Fantastic product. I also purchased a tube of Versachem 15339 dielectric grease to help keep the connectors clean.

  9. Amazon Customer

    Highly recommend. Great product. Purchased one back about 2 years ago and have not had any issues with it. I can now keep one in each vehicle that I tow with. Only drawback, it would have been nice to have some sort of pouch to hold all the tools. Other than that, I highly recommend this product.

  18. KCS

    Great unique tools These are truly unique little tools. It never ceases to amaze me how corroded many peoples connectors are. Look for a spray by Eureka chemical called “Fluid Film”. This is a sleeper product when it comes to eating corrosion and protecting.
