Review on Wisepick Valve Conditioner R134A Refrigerant by James Kelley

that saved me a lot of money compared to buying it at a local store. The only drawback are the pads, I replaced them shortly before use. Gaskets do not provide a tight fit, a small bump will cause refrigerant to leak. Update * One of the valves has already failed and coolant is sloshing out of the handle. I tried to tighten it but the screw broke immediately. This is a cheap material.
