These are excellent gauges for HVAC work. The valves seal perfect and the gauges are spot on accurate. The hoses and adapters are all high quality. Great value for gauges.

Good

Worked great. Exactly what I needed.

I purchased this gauge set along with an OMT 3.5cfm 1/4hp vacuum pump as a pair in install my mini split heat pump.I found a small scratch on the tip of the 5/16 to 1/4 adapter, which is required to connect the hose to the mini split service port. They included two of these adapters so I was able to continue using the other adapter. This stopped the seeping which caused the vacuum to leak down after 5-10 mins. I contacted OMT tech support and they seem to think that one of the adapters needs replacing, and they will ship it.Using the other adapter the vacuum quickly reads on the gauge and the needle stays put when I turn off the pump and close the valve.Since the system maintains the vacuum for an extended time after I shut off the pump I think there are no other leaks.

I’m disappointed in the PSI scale and vacuum readings on the dial. PSI scale is too small to read and vacuum scale has no increments.

I don’t often do AC work but need to on my home equipment when there’s an issue with it. My old gauges were Robinair and the hoses leaked plus I didn’t trust the gauges on 410. I bought the kit and it contained everything that I believe I would ever need for AC maintenance and repair. I’ve used the new kit once and everything worked fine.

Works well, good gauges for the price.

Save your time and efforts!!!! Do not buys this unless you have patience and eyes like a eagle! Dial is hard to read, fitting will not fits snug.
