Great little set of gauges for occasional use. Not for pros. IMPORTANT DETAIL: If you want to hook these up to a vpump, you'll have to get an adapter. THE YELLOW SWIVELING HOSE FITTING IS A LEFT HAND 1/2in ACME THREAD. I've never heard of a vacuum pump having a left hand acme thread. I bought a 1/4in SAE to 1/2In LH ACME adapter and it works great.

like these gauges well made easy to read.

Fits snug the first time used very nice
