This was a gift to someone

Used this to recharge my mini split A/C with 410a refrigerant. Xlnt gauges, brass quality, hoses. Xlnt fit, smooth thread engagement. Feels well constructed throughout. I never worked with home A/C before. Had the 410a recharged in my minisplit in 15 minutes in large part because this manifold set was so easy to use.

I installed a DIY ductless mini-split A/C unit on our house. Part of the installation requires vacuuming the line sets while monitoring with a set of gauges. Local store had the vacuum pump for rent but no one had gauges appropriate for the refrigerant used in a home unit. I bought this to fill that need and it worked perfectly. Be advised that it comes with no directions whatsoever but the A/C installation manual walked through the process so I didn't have to figure it out on my own. Hoses were in good shape and everything works. Came with two adapters and some spare gaskets for the connectors. Definitely worth the money.

I ordered these gauges to vacuum down a mini split unit I installed. I noticed after turning on the vacuum pump that the gauge on the low side was about 20 inHg but would not reach full vacuum. After about 15 minutes having the mini split under vacuum. I shut the valve off on the low side and then the vacuum pump and vacuum held. There was no rise in pressure. I tried again but noticed the gauge had not zero out. It was pass zero. I decided to test the gauges to make sure the gauges where not leaking. I will explain the process incase someone runs to a similar situation. I connected both the the blue hose (low pressure side) to the bottom and back on the manifold. I did the same for the red hose, the high pressure side. I connected my yellow to the bottom of the manifold and the other end to the vacuum pump. I made sure to close both the low side and high side and started my vacuum pump. After starting the vacuum pump I opened the low side and ran the vacuum pump. After a couple of minutes I closed the low side and then shut off the vacuum pump. The vacuum held with no rise in pressure. I did the same for the high side and again no rise in pressure. After verifying the gauges where not leaking I took notice where the gauge on the low side zero out and marked it. I then proceeded to vacuum down the mini split knowing that the zero mark was around the 10 psi mark and the 30 inHg was about the 20 inHg mark on the gauges. The process was a bit frustrating due to the inaccuracy of the gauges but I made it work.

Overall the set seemed fine enough, but when attaching the high-pressure line to the service port exposed a leak at the crip end of the hose with the service port connector. Obviously not a great situation with spray coming from the hose side of the connector while getting the normal spray hooking into the service port. This was totally unexpected, if I wasn't wearing gloves... that could have been really bad! After all that, I still had unfinished work! So I used another hose and found the gauges were reading well enough. But I'm disappointed in the quality.

I bought this gauge set to enable me to verify my mini split heat pump installation was leak free before I released the R410 refrigerant. This gauge set is for residential R410 applications. It worked well and was good value. The product arrived in 2 days with Amazon Prime. I bought the gauge set but the vacuum pump I got from Autozone at no charge - just a refundable security deposit. This gauge set also came with two adapters for connecting to the mini split evacuation port.
