“I opted for these over the popular Matco rebrand of Mastercools. Couldn't be happier. 4 valve/4 hose much simpler than 3 hose setup. Large gauges easy to read. Rubberized grip knobs work flawlessly. Coupled with r134 quick connects.”
“Used for vehicle A/C with Edwards RV8 vacuum pump. Like the gauges but the sight glass ring is octagon, no tool to remove for cleaning or o-ring replacement. Major letdown.”
