Review: 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. ## Features - SMAN Manifold + Vacuum Gauge (4 Port) - Supports over 70 refrigerants - A2L Compatible - Contains a 3/8 vacuum port and block for fast evacuations - Features an integrated vacuum gauge - Measures line pressures, pipe temperatures, dry bulb temperature, and system vacuum ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DFMPJP2W | | Best Sellers Rank | #162,287 in Automotive ( See Top 100 in Automotive ) #64 in Automotive AC Manifold Gauges | | Brand Name | Fieldpiece | | Customer Reviews | 4.7 4.7 out of 5 stars (124) | | Included Components | 1 - 4-Valve SMAN Series Wireless Digital Refrigerant Manifold (SM482V), 1 - Padded Case (ANC82), 1 - Type-K Alligator Clip Bead Thermocouple (ATA1), 2 - Type-K Wired Pipe Clamp Thermocouples (TC24) | | Item Dimensions | 12.7 x 26 x 28.6 centimeters | | Manufacturer | FIELDPIECE INSTRUMENTS,INC | | Material Type | ABS Plastic | | Model | SM482V | | Part Number | SM482V | | Thread Style | BSPP | | UPC | 872641005504 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Fieldpiece - **Item dimensions L x W x H:** 12.7 x 26 x 28.6 centimeters - **Material:** ABS Plastic - **Number of Items:** 4 - **Thread type:** BSPP ## Images ![Fieldpiece SM482V 4-Valve SMAN Series Wireless Digital Refrigerant Manifold - Image 1](https://m.media-amazon.com/images/I/71+Fi5A9mvL.jpg) ![Fieldpiece SM482V 4-Valve SMAN Series Wireless Digital Refrigerant Manifold - Image 2](https://m.media-amazon.com/images/I/81wpnq7RJLL.jpg) ![Fieldpiece SM482V 4-Valve SMAN Series Wireless Digital Refrigerant Manifold - Image 3](https://m.media-amazon.com/images/I/81W-7nEJm7L.jpg) ![Fieldpiece SM482V 4-Valve SMAN Series Wireless Digital Refrigerant Manifold - Image 4](https://m.media-amazon.com/images/I/81lQq6fZ9IL.jpg) ![Fieldpiece SM482V 4-Valve SMAN Series Wireless Digital Refrigerant Manifold - Image 5](https://m.media-amazon.com/images/I/81CAYVB5QKL.jpg) ## Available Options This product comes in different **Model** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***M on 18 April 2026* Best gauge set out there.
