Questions about this item

What does the 30 to 0 range mean when the gauge is installed?

It reads full vacuum up to 30 inches of mercury and shows zero at atmospheric pressure, so the needle moves across the entire scale as the system evacuates.

What does the 1/4 in NPT male connection limit in practice?

It mates with standard 1/4 inch NPT female ports on pumps, chambers or manifolds, and the tapered threads seal without extra fittings.

What clearance does the 4 1/2 in dial and bottom mount need to fit?

The 4 1/2 inch stainless case sits below the 1/4 inch NPT stem, so allow enough depth behind the panel for the case body and the glass lens.
