Ashcroft 351009SW02L5000# Pressure Gauge 0-5000 psi 3 1/2 in

Industrial Pressure Gauge 0-5000 psi

This Ashcroft 351009SW02L5000# gauge measures pressure from 0 to 5000 psi with a 3 1/2 in dial. The 304 stainless steel case and polycarbonate lens protect the mechanism in demanding environments. It suits technicians and plant operators who need reliable local indication on hydraulic or pneumatic systems. The 1/4 in NPT male bottom connection fits common process ports directly.

IP54 and IP65 Rating Limits

The gauge meets IP54 when the vent plug is open and IP65 when the plug is closed, also satisfying NEMA 4 in the closed state. This means it resists dust and water jets only when sealed, so installations exposed to wash-down must keep the plug shut. Opening the vent for atmospheric reference reduces ingress protection, limiting use in continuously wet or dusty areas unless the plug remains closed. The fixed 1.0 percent accuracy applies across the full scale regardless of vent position.

Capacity and Headroom

The 5000 psi primary range handles high-pressure hydraulic circuits and compressor discharge lines without over-range risk. Accuracy holds at +/- 1.0 percent of span, so readings stay consistent near the top of the scale. No dry dampening or vibration resistance features are included, so rapid pressure spikes or mechanical vibration can affect pointer stability and long-term calibration. The gauge is not field fillable, preventing user-added fluid damping for pulsating services.
