Review on 🔧 WADEO Valve Core Remover Installer Tool - Dual Size SAE 1/4 & 5/16 Port + 20 PCS Teflon Seal Valve Cores & 10 PCS Brass Nuts - Compatible with R22 R12 R407 R410 R404 R32 R600 A/C by Wayne Drakh

I had some homework to do since I don't do HVAC and realized that no split air conditioning project could be done properly without this unit, but put a lot of thought into it and understanding is required to use it CORRECTLY in order for it to provide the best possible results. Luckily spare valves are included as I bent a couple. And they are very useful for practice. Please practice removing and inserting the cores from the dummy pipe fitting first, not the real one. does not fall out in the device before removing it... Exercise will give you a feel for it :-) -- It's easy :) Block /C - all these tubes should be kept closed as tightly as possible to avoid dust and secondary materials :) Good value for money - can't blame anyone but the operator!
