Orion Motor Tech R410a Gauges, AC Manifold Gauge Set for R22 R32 410A 134A Refrigerant, 3 Way AC Gauges R410a Manifold Set with R410a R22 Safety Valves, 3 Hoses, R410a Adapters, Universal Can Tap

Great value. Look like thare high qulaity, Durable product, good quality build. One of the only gauges that was ACTUALLY R32 rated. Nice length hoses, not like others that are only about 3 ft long. Fairly easy to use, i wouldnt day fool proof, since you SHOULD know what you are doing, but very user friendly. I didnt check against other gauges so cant really speak to accuracy, but they work very well.

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.

Very nice case and gauges... Works as stated. Worth the money to work on AC units.

Worked great. Exactly what I needed.

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.

Good

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.

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.
