Review on 🔌 Efficient R1234yf Quick Couplers: High/Low Side Manual Couplers for A/C Refrigerants Manifold Gauge Set, 1/4" Male Port, Quick Connect Adapters & AC Hose Fitting Connectors Replacement by Scott Welch

These are cat pajamas. I have a 2018 Ford Truck that crashed so I had to top up the system. If you look at them, you probably know how expensive the new 1234 fluid is. After much research I decided to upgrade to R134 for a fraction of the cost. I was able to use less than 134 and still get the correct system pressure. The 134 oil is about 10% more efficient than the 1234. I still used the oil on the newer 1234 as it is compatible with the 134. These clutches made everything possible. Thank you Revan
