  • +/- 1.0% accuracy ensures reliable pressure readings
  • 304 stainless steel case resists corrosion in harsh environments
  • IP54 vented and IP65 sealed ratings protect against dust and water ingress
  • PLUS! Performance dampening reduces pointer vibration for stable indication
  • 0 to 300 psi range suits industrial process monitoring

Application and User

The Ashcroft 251009 is an industrial pressure gauge built for technicians and engineers who need reliable readings in hydraulic or pneumatic systems. It suits maintenance crews, plant operators and test-bench users who require a durable, field-serviceable instrument. It is not for buyers who need digital data logging or wireless telemetry.

Accuracy Specification

The gauge delivers a stated accuracy of +/- 1.0 percent across a primary range of 0 to 300 psi. This tolerance is the single figure that determines whether the instrument meets your calibration or process-control requirements.

Environmental Protection and Operation

A 304 stainless steel case with a polycarbonate lens provides IP54 protection when the vent plug is open and IP65 when closed, meeting NEMA 4 in the sealed condition. The PLUS! Performance dampening feature steadies the pointer without liquid fill, reducing vibration-induced wear and keeping readings stable during normal operation.

Questions about this item

What does the ±1.0 percent accuracy mean when the gauge is installed on a live system?

The reading will stay within 1.0 percent of the true pressure across the 0 to 300 psi range, so at full scale the maximum error is 3 psi.

How do the IP54 and IP65 ratings differ depending on the vent plug position?

With the vent plug open the gauge meets IP54; with the plug closed it meets IP65 and NEMA 4, giving full dust protection and resistance to water jets.

What mounting hardware is required for the 1/4 inch NPT male bottom connection?

A 1/4 inch NPT female port or fitting is needed; the gauge threads directly into it with no additional bracket required.
