Review on 🔧 Mastercool R134A Standard and JRA Valve Core Remover in Black by Sean Andrews

So in the end this tool is great. I was able to remove and replace the Schrader valves. However, I would suggest playing around with the device and the various connectors so that they understand 1 - which of the main poles they need to use. How do you define it? You should be able to see which one fits in the valve hole. Don't delete anything with it yet, just find out which one. 2- Now you need to make sure you understand how the stem goes through the valve and how it opens and closes so you don't get confused when you sit there with the valve removed and not knowing which way to turn the device have to rotate to force it release. Valve for you 3. Make sure you actually have both types of valves, JRA and standard, as it just doesn't match which one is there. None of the components are tagged, so you should fiddle around first and then use them. Watch a video of it so you can see how you have to hold the stem from time to time because the pressure is pushing it out. I'm very glad I bought this tool, I just wish it was better labeled. But guessing wasn't difficult.
