Worked like a charm to replace a condensers leaking valve core

Worked like a charm to replace a condensers leaking valve core
Quality, well built, name branded tool that worked like a charm!Had a central ac condenser with a leaking valve core. Watched a few videos and one specifically by this parts manufacturer, Appion. Please watch their video first, then start practice seating replacement valve core into the tool to understand how it feels and holds. You do not want any potential for the valve core to fall off in the process so the "fork" on the end of the removal tool may have to be spread or snugged SLIGHTLY to hold the core tight. If so, use a pair of pliers to GENTLY do so. This adjustment is so minor you won't be able to see a difference - but you will feel it when inserting the valve core.Once comfortable with your skill fitting the tool, you'll need to fit the removal tool to the leaking valve core just as you practices with the new one. Once you are confident it will hold snuggly, re-assemble tool and you can start the repair.Peace
