Common Questions
Is it made in the United States?
The gauge is made in China and it's really disappointing. Not a Robin air product at all.
Is it certified by the nsf?
I lost the seal after just the first time using it, I didn't notice it came out of the hose, there's no replacement, and the gauge is cheap.
Is it possible to switch red and blue hoses to 96?
I don't see why you wouldn't, they have screw on connections just like every other manifold gauge set I have used.
Is the mechanism that connects the schrader valve to the quick connect or screw type?
The system gas/liquid line is connected to the hoses/manifold/gauge by means of a spring mounted collar.
Does it come with the blowmolded case?
I haven't taken the gauges out of that case and can't offer an opinion on them, but they come in a nicely contained case.
