Review on 🟡 FJC 6527 Yellow 72" R134A Charging Hose: Efficient Refrigerant Charging Solution by Steven Nina

92649 It also connected well and worked well when connected to my Harbor Freight/Pittsburg 2.5 CFM vacuum pump. For DIYers: Be sure to connect the "open end" of the hose to the gauge manifold and the "valve end" to the vacuum pump and/or freon dispenser. The valve allows you to evacuate and close the system when the hose is disconnected to connect the freon supply without losing the vacuum. It's a good idea to have a 134A can dispenser if you use small 12oz cans for refilling - preferably metal with a valve. Adjust the valve as needed for the sweet spot when dosing Freon.
