PRM 2.5" Chrome Vacuum Gauge - 0 To -60" WC / 0 To -4.5" Hg, 1/4" NPT Back Mount

Need to keep an eye on vacuum levels?

This PRM gauge is a new, 2.5-inch unit with a classic chrome-plated case.

It reads from 0 down to -60 inches of water column, which is also 0 to -4.5 inches of mercury.

It's a dry gauge (no liquid inside) with brass internals and a 1/4-inch NPT thread on the back for mounting.

The connection is brass as well.

Whether you're tuning an engine, monitoring a pump, or working on industrial equipment, this gauge gives you a clear, mechanical readout.
