Model: SM482V
Works great. Upgrading my entire AC setup so I'm ready to go into business when the time comes. This manifold I paired with the Fieldpiece Joblink set which includes the wireless air temperature sensors for return/supply, pressure sensors for suction/liquid, and temperature clamps for suction/liquid. One issue I had initially was on system vacuuming, and I almost returned these for the 3 port SM382v, but decided against the return. The issue is present when using hoses and manifolds that have had refrigerant ran through them. When pulling a vacuum, refrigerant will start to evaporate at inconsistent times. This leaves you wondering if that 5 micron delta/min on a decay test is a leak or not. Most of the time, it did a great job of pulling down to 200 microns (manifold side) then on closing the manifolds vacuum port, we'd shoot up to about 350 or 400 while it equalized. After equalizing, we'd see a constant ~2 to 5 micron rise per minute. Other times, I'd get down to 400 microns and pop back up to 520, and it would pump back down to 390 and pop back to 510, pump down to 380 and pop back to 500. This cycle repeats itself and I can't tell if it's a micron gauge fault or evaporation. It isn't a leak, because it holds solid microns, but it does pop around quite a bit. Purge with nitrogen through your manifold and lines at high pressure before starting vacuum to mitigate this. Instead of returning this manifold because of the vacuum inconsistencies, I went for the redundancy approach and got two large vacuum hoses and a wireless micron gauge, leaving the manifold for watching system charge or vacuum alternative. Although I could just use the full wireless set for that now, anyways.

My husband loved this product. The durability, the easy connectivity of job link, (you can be in the attic connects great) and toggle through all the functions with easy reading! He said there just DOPE!!!

Works very well as an AC pressure set. I am a home gamer with an EPA license doing my own HVAC work and I wanted the best equipment. I use this for HVAC and MVAC without any issues. This is a huge over kill for most of what I do, but I wanted something accurate that is refrigerant agnostic as I used anything from R22 to R134 to R32 with the various systems on my property. I highly recommend this as your last AC gauge set.

Love Fieldpiece products but if you want to buy tools like this, find a local parts house or a actual online dealer that Fieldpiece recognizes. These gauges started leaking at the refrigerant knob about 4 months after entering the field and Fieldpiece did not warranty them because they were bought off of Amazon, Fieldpiece rep told me the best he could do is recommend the manifold rebuild kit.

I had purchased this fieldpiece manifold gauge # 480V on June 5, 2025. I have been a heavy-duty technician in this field for over 45 years. However, I had already had the SMAN 360 manifold gauge since 2021, and it was only replaced once. But the products had made my job with the new investment much easier. The step up to the 480V has many more features, like the tightness test, which is very important for leaks in the a/c system with nitrogen gas. I had done my homework on other professional HVAC professionals and the automotive technicians, with many online videos and comments from them. I decided to get the product and try it myself, and I was very pleased with the outcome. I have purchased many of the Fieldpiece products, and so far, I am happy with my investment in the Fieldpiece product for the HVAC system in the automotive industry. Again, I thank the HVAC professionals and the automotive technician for their comments and videos on the Fieldpiece products they shared online, which positively influenced my decision. Again, thank you all.
