Review on 🌡️ FJC Inc. 6025 Quick Coupler Manifold Gauge Set Conversion Kit: Optimize Refrigeration System Performance by Kyle Deel

This is Katherine's Husband. I like the design and it seems to be of exceptional quality. They feel so smooth when you press them into the joint and they snap into place very firmly. They also spin smoothly with no leaks. However, the image colors are disabled. When I received mine they were painted red/blue (no complaints here). The included adapter allowed me to use the R134a 30 lbs. can be developed for the automotive industry to connect my commercial sensors (Sman4). Ok, now for the bad. Once the pressure rises above 100 pounds, they become increasingly difficult to release. The low side isn't usually a problem, but after pressurizing the system to 300 pounds with nitrogen, they couldn't be deflated. I had to wait until I was ready to release some pressure before filming. If it wasn't for the fact that I couldn't take them off under pressure I would have given them 5 stars as I liked the quality. I will be returning the item and getting a clamp type so I don't have to deal with this issue again.
