Industrial Pressure Gauge 0–100 psi

This Ashcroft 351009 gauge measures pressure from 0 to 100 psi with a 3 1/2 inch dial and +/- 1.0 percent accuracy. The 304 stainless steel case and polycarbonate lens provide durability for industrial environments. A 1/4 inch male NPT bottom connection suits standard process piping. It is built for technicians who need reliable local indication.

Upgrade from unrated or plastic-cased gauges

The IP54 vented and IP65 sealed ratings protect internals from dust and water ingress better than basic models. Stainless construction resists corrosion that damages plated brass or plastic housings over time. The jump is worth it when the installation sees wash-down, humidity or outdoor exposure. Dry dampening means no fill fluid to leak or freeze.

Fits panels and pipe mounts with 1/4 NPT threads

The bottom-mounted male connection threads directly into existing process taps without extra adapters. Metallic case colour and white dial ensure readability in typical plant lighting. The vented plug allows pressure equalisation while the closed plug meets NEMA 4 requirements. No field-fill option means the gauge arrives ready to install.

Questions about this item

What size NPT thread does the 1/4 in process connection on the Ashcroft 351009 gauge use?

The gauge has a 1/4 in male NPT process connection that threads directly into a matching female port.

Which step is often missed when installing this bottom-connected gauge to meet its IP65 and NEMA 4 ratings?

The vent plug must be left closed after mounting; opening it reduces the rating to IP54.

When should the polycarbonate lens be replaced on this 3 1/2 in dial gauge?

Replace the lens if it becomes cracked, heavily scratched, or clouded so the white dial and +/- 1.0 percent accuracy remain readable.
