Review on Supco VGC Vacuum Gauge Coupler by Chris Scalia

This Industrial and Scientific vacuum gauge coupler was a complete letdown. When i tried to use it on my equipment, the reading was inconsistent and inaccurate leaving me feeling frustrated. While the compact size and design might seem like a pro, the unreliable performance outweighs any positives... Save yourself the trouble and invest in a better vacuum gauge coupler..
