Review on Mastercool Blue R410A, R22, R404A 2-Way Manifold Set with 3-1/8-Inch Gauges and 60-Inch Hoses by Kent Kings

I used a similar set many years ago but they were branded as r134a snap on tools. I absolutely loved them and they were really tough. It's basically the same with the same design. Now I use them as HVAC service technology and expect the same result as my other set. As mentioned, this kit does not include the 3/8 vacuum hose that it says is included. A kit with it and an adapter costs an additional $50. I wasn't planning on using it anyway. It also eliminates the need for 60" hoses, especially when servicing a mini-split system. For this reason I will order 36 inch hoses from Mastercool. I only give 4 stars because of the lack of a black vacuum hose.
