Review on 🔌 High/Low Side Quick Couplers R134a Recharge Kit - Lu-Hawk Automotive with Self Sealing and Single-Use Can Tap Valves, Plus Valve Core Removal Tool by Geoff Foster

I just hooked them up to my sensors and they worked as expected. I haven't had any issues with leaks or anything like that. Good product, if you need new adapters try them. Crane is a bit touchy. Works with both sealed and pierced types. You just have to find the middle ground. The problem I have is that no matter what I try it tries to cross the thread when you tighten it all the way. My suggestion is to just tighten it enough to seal.
