Valve Core Remover Installer Tool & HVAC Service Wrench Set with Hex Bit Adapters, Dual Size SAE 1/4 & 5/16 Port,3/8'' to 1/4'', 5/16'' x 1/4'' Refrigeration Service Wrench,10pcs Valve Core

Last year was hot and I had more than a few AC service calls and replacements. This tool came in so handy last year to replace cores that were not in the best of condition. Even without the core tool, the wrenches were my best friend. Everything was well built, came with extra cores (I replaced with ones from the HVAC shop that I trust) and off it went. No leaks were detected when using it, the operation was simple and it worked in tight areas.

As advertised, works well, well built

As others have said, does not work for vacuum, the valve leaks. Other than that, it works as described and the included schraders seem to be ok quality.

These are the best valve core removal, tools for the money for sure. They have outlasted my Appion tools. I’ve probably used them between 75 and 100 times in the last year since I have bought them, pulling vacuums and they have never leaked at once. I gave up with the big name brands because they are so expensive and having to rebuild gaskets so often, etc. but the trick with these, as with all the others do not over tighten and it will save the gaskets. Everybody always wants to crank down on them, but I promise you it will make a good enough seal, getting them snug by hand.

I was pleased by the quality of this product. it is a good size and very functional. As a refrigeration technician I think this is just as good as the JB or Yellowjacket counter parts at a fraction of the price. The accessories were a nice touch. No leakage after around a year of use. Cheap, easy to use quality product.

This is a must have for HVAC techs. It works just as well as higher priced models. It comes with extra Schrader valves too!

Bueno

Decent core removal tool and accessories. Everything works as expected with no issue
