Review on 🔧 C&D Valve CD3930 - 1/4" Ball Valve / Core Removal Tool (BV-CRT): Efficient Solution for Easy and Accurate Core Removal by Chris Fields

It didn't work on my system, but it's not the tool's fault. Since I could charge the system myself, I decided to completely remove the Schrader valve (from my home air conditioner) with pliers, but I couldn't do it - it really got stuck there! The build quality of the tool is excellent. Exceeded all expectations! If you're in my situation (Schrader leaks but can't be removed), I recommend getting C&D brass Schrader caps. If installed correctly, they CAN ALSO seal a leaking shredder - this has worked on my system for the last (2) months.
