23PCS Valve Core Remover Installer Tool & Hvac Service Wrench Set with Hex Bit Adapters, Dual Size SAE 1/4 & 5/16 Port, 1/4’’, 5/16'', 3/8'' Refrigeration Service Wrench, 15 Valve Core, Storage Bag

Great HVAC tools. Sturdy and durable. My son chose these and he loves them.

I thought I had it tight enough but I didn't. I was doing a pressure test, and everything worked well up until about a 180 pounds and then it blew out and I lost all my nitrogen. It turns out the device was not screwed onto my system tight enough. Be sure to screw it on completely. All the other features seem to work as advertised and expected. The threads and the connectors seem formed well and everything fit well and screwed on easily. It locked on my schrader valve securely and was able to pull the valve out and not fall off. The on off valve had a solid feel and in the off position did not leak at all.

Excelente producto
