Review on 🔧 Mudder A/C Valve Core Remover Tool Kit with Dual Size SAE 1/4 & 5/16 Port, R410 R32 Brass Adapter, 20 Valve Cores and 10 Brass Nut HVAC Valve Core Removal Installer Kit by Ario Rojas

When I examined the tool I saw a protruding part of the stem seal. Further investigation showed that up to this point I could see daylight through the array. This thing should be a dangerous disaster if used. This would certainly allow pressurized r134a coolant to spray back at me once I tightened it on the service fitting. I'm sure of it because I could only blow with my mouth through the top part where the stem enters.
