Ashcroft 451279 Pressure Gauge

The Ashcroft 451279 is a new process pressure gauge built for industrial monitoring where precise readings matter. It covers a 0 to 1500 psi range on a 4 1/2 in white dial with glass lens and +/- 0.5 percent accuracy. The phenolic case is black and the 1/2 in male NPT connection mounts at the bottom.

Suits plants needing reliable dry

This gauge fits operators who want a field-ready instrument with PLUS Performance dampening and no liquid fill requirement. It is not for buyers who need an IP or NEMA rated enclosure, a back or panel mount connection, or a different pressure span.

Bottom NPT thread simplifies pipe fitting

Installation means threading the 1/2 in male NPT connection into a matching female port on the process line. The dry case eliminates fill leaks but offers no IP protection, so exposure to wash-down or submersion should be avoided.

Questions about this item

What thread size and type does the 1/2 in NPT male connection require on my existing pipe or fitting?

The gauge uses a 1/2 in NPT male process connection, so the mating port must be a 1/2 in NPT female thread.

Will the phenolic case and glass lens hold up next to older brass or steel fittings without galvanic issues?

The black phenolic case and glass lens are non-metallic, so they will not create a galvanic couple with brass or steel piping.

How can I verify the +/- 0.5 percent accuracy after I install the gauge?

Apply a known reference pressure at several points across the 0 to 1500 psi range and confirm the needle reads within +/- 0.5 percent of full scale.
