Ashcroft 4 1/2 in Process Pressure Gauge

This Ashcroft process pressure gauge measures from 0 to 1,500 psi with a nominal dial size of 4 1/2 inches. It provides an accuracy of +/- 0.5 percent for reliable readings in industrial applications.

Electronic Gauge with Glass Lens and PBT Case

The electronic gauge features a black polybutylene terephthalate case and a glass lens for durability. A white dial ensures clear visibility, while the bottom-mounted connection simplifies installation in piping systems.

1/2 in NPT Male Connection for Direct Mounting

The process connection uses a 1/2 inch NPT male thread for direct attachment to compatible fittings. The gauge is not field fillable and carries no IP or NEMA rating, limiting use to protected indoor environments.

Questions about this item

How is the 1/2 in NPT male process connection installed, and what step is often missed?

Thread the 1/2 in NPT male connection into the matching female port using suitable thread sealant, then tighten with a wrench on the gauge case flats — not the dial — to avoid damaging the polybutylene terephthalate housing.

What maintenance will the glass lens and dry gauge need over time?

Clean the glass lens with a non-abrasive cloth when dirty; the dry dampening design has no fill fluid to replace, so no periodic refill is required.

At what pressure does the +/- 0.5 percent accuracy limit become the governing constraint during sustained use?

The +/- 0.5 percent full-scale accuracy applies across the entire 0 to 1,500 psi range, so the measurement uncertainty remains the primary limit at any sustained pressure within that span.
