Review on Diagnostic Manifold Evacuation Refrigerants Adjustable by Scott Snyder

I was looking for kits from Revain and thought it would be cheaper if they came in one kit and I was wrong. I took these gauges over the average pump to charge my daughter's air conditioner for about $30 less than the kits. I'm not an expert so I can only confirm what I liked, good quality hoses, gauges and knobs seem to be of good quality. A 4 house system makes more sense than a 3 house system, you can connect all your devices and get started right away. There is a vent valve on the tank line that allows you to bleed air out of the line. Swivel fittings make it easy to tighten and loosen with your free hand. No Teflon required, seals work great. The supplied adapters are suitable for connection to the tank hose, so that no additional purchases are required. The entry of Freon into the system can be seen very clearly through the sight glass. The only complaint I have is the tank tap that comes with the kit. Not sure if they are faucets. It won't work with your standard R134a tanks, the only thing that comes with the kit, but it's not what I need. I would recommend this product to anyone who wants to repair AC there.
