VC2G 1/4″ Valve Core Removal Tool Dual Valve with Sight Glass - Vacuum-Rated 20 microns & A2L Compatible - Ideal for HVAC Tool Kit

It doesn't fit on all 1/4 service valves. I work with chillers and the ones like Carrier 30HX have the cores deeper than the core remover could actually go because there is an increase in the remover diameter and it doesn't fit into the hole. On the other hand it worked well on residential units like small ( 3-6 tons) splits and minisplits. Hope it helps to those who want to invest into quality tools.

Has the quality you’d expect being from fieldpiece. This actually grabs and holds onto the Schrader valve when removing from a pressurized system, and the sight glass makes it so easy to confirm you’re pulling the valve. It’s heavy duty and can take a beating. I tried six other valve removal tools before this one and it’s way better by far compared to any of the cheaper models out there. If you do a lot of hvac work, buy this, and save yourself the otherwise annoying task of removing the Schrader valve

There is no better core removal tool. It’s simply perfect in every way. The ability to isolate the micron gauge without additional parts or losing vacuum at all is so great. Can’t say enough. I have 2 of them.

I didn’t believe all the one star reviews but I should have. Bought this and was so excited to use it! First time using it I couldn’t pull the valve out with pressure or without pressure in the system. At first I thought it was something I was doing wrong but no matter what I did it wouldn’t grab the core out and allow me to change it. Love field piece products but this missed the mark for them. Co worker has a navac one that was beyond easy to grab and remove the valve. Thought I would get the top of line one with a cool sight glass but it was terrible and wasted a good hour fighting with the tool to get it to work right.

The best tool of its kind on the market; there's nothing else like it. Great job, Fieldpiece!
