Product Identity

The Ashcroft 251009 is an industrial pressure gauge designed for measuring hydraulic and pneumatic systems up to 2000 psi. It features a 2 1/2 inch dial housed in a 304 stainless steel case with a polycarbonate lens. The gauge uses a bottom-mounted 1/4 inch male NPT process connection and offers a field-fillable design for liquid dampening in high-vibration environments.

Suitability Profile

This gauge suits technicians and plant engineers who need a durable, vibration-resistant instrument with IP54 or IP65 ingress protection for industrial process monitoring. It is not intended for buyers who require a digital display or electronic signal output for data logging. It also does not suit applications needing a centre-back or panel-mount connection style.

Sustained Operation

The liquid-filled design provides continuous pointer stability by dampening the effects of persistent vibration and pressure pulsation during extended service. The 304 stainless steel case and polycarbonate lens maintain structural integrity and readability in corrosive or wash-down environments. Accuracy remains within +/- 1.5 percent of full scale across the 0 to 2000 psi range under steady operating conditions.

Highlights

Questions about this item

Does my system need a 1/4 in NPT male port to mount the Ashcroft 251009?

Yes, the gauge has a 1/4 in NPT male process connection at the bottom, so the mating port must be 1/4 in NPT female.

Will the +/- 1.5 percent accuracy hold when I plumb it into an older 2000 psi hydraulic circuit?

The stated accuracy is +/- 1.5 percent of the 0 to 2000 psi range, and it applies regardless of the circuit age as long as pressure stays within that range.

How do I confirm the IP65 and NEMA 4 seals are intact after installation?

Close the vent plug, then inspect that the polycarbonate lens and 304 stainless case show no gaps or leaks under operating pressure.
