Fits the everyday condensers. i was worried about fitment. has a little less quality feel to it but just change the gaskets regularly and they should have no problem sealing.

What a great concept. In the past you had to leave the core in place while evacuating the system so as not to reintroduce air into the system. I love it. Makes vacuuming out the system quicker. I wish I had this years ago.

I bought these because I needed to replace my yellow jacket ones that the stem had bent on (my own fault had a bag get dropped off a roof). I will never buy these or cheap valve tools again. I had them about 3 months before the ball valve failed to completely seal and I got liquid refrigerant on my thumb (still dealing with the blister from that) and had to completely empty a system because I couldn't remove my gauges to put the core back in. Prior to this happening I had the tool drop schrader cores 2 times while removing them and had to spend time trying to grab the loose schrader core with the tool, the second time it happened I couldn't get it and decided to just fire it into orbit by opening the valve and just put in a replacement core. Don't buy these or any other cheap core tool, get good name brand ones like yellow jacket, appion, hilmar, or JB, don't waste your time or money with this junk, it cost me more money than I saved on 1 job alone.

Works as it should. Bought to replace my yellow jacket model which fealt tighter built and had valve storage built into the end. Cheaper price and works as it should

No leaks / simple to use
