Industrial pressure gauge 0-30 psi

The Ashcroft 251009SW02L30# is a 2 1/2 inch dial pressure gauge designed for industrial process monitoring. Its 304 stainless steel case and polycarbonate lens provide corrosion resistance in harsh environments. The bottom-mounted 1/4 inch NPT male connection suits inline piping installations. Accuracy is rated at +/- 1.0 percent across the 0 to 30 psi range.

Suited for fixed process lines needing IP-rated

This gauge fits operators who require a durable, dry instrument with selectable ingress protection. The vented plug delivers IP54 while the closed plug achieves IP65 and NEMA 4 ratings. It is not intended for applications requiring liquid-filled dampening or integrated vibration resistance. Buyers needing a field-fillable case or a different pressure span should consider other models.

Vent plug position changes the environmental seal

With the plug vented the gauge meets IP54 for basic splash and dust protection. Closing the plug upgrades the seal to IP65 and NEMA 4 for wash-down and outdoor exposure. No additional accessories or software are included; the case itself provides the dual-rating capability. The fixed 1/4 inch NPT connection and dry operation are unchanged by the plug setting.

Questions about this item

What size NPT fitting do I need to connect the 1/4 in process connection on the Ashcroft 251009SW02L30#?

The gauge has a 1/4 in male NPT process connection, so you need a matching 1/4 in female NPT port or adapter on your system.

Will the IP54 and IP65 ratings protect the gauge if I keep it next to older equipment that leaks oil?

With the vent plug closed the case meets IP65 and NEMA 4, resisting oil splash and dust; with the plug vented it meets IP54 for lighter exposure.

How do I verify the +/- 1.0 percent accuracy on the 0 to 30 scale after installation?

Apply a known reference pressure across the 0 to 30 range and confirm the pointer reads within +/- 1.0 percent of full scale at each test point.
