Review on Advanced Aain LX14 R134 Diagnostic A/C Manifold Gauge Kit: High-quality HVAC Gauge Set with 5FT Hose for R134A, R404A, R407 Refrigerants by Angel Cortez

I bought this after my old tool failed and wasted a can of R134. It plugs directly into the new self-sealing bins, eliminating the need for an adapter. We used it to charge the AC system of an old F350 truck. When I was done I removed the tool from the R134A canister, the coolant wasn't wasted and I can use the remaining coolant another time.
