Industrial pressure gauge 0-1500 psi

The Ashcroft 251009 is a 2 1/2 inch industrial pressure gauge built for measuring hydraulic and pneumatic systems up to 1,500 psi. It suits maintenance technicians, plant engineers and OEM integrators who need a panel or line-mounted instrument with a stainless steel case and polycarbonate lens.

Accuracy class ±1.5 % and IP ratings

Accuracy is rated at ±1.5 percent of span across the full 0 to 1,500 psi range. The gauge is liquid-filled for vibration resistance and field-fillable for on-site adjustment. Environmental protection reaches IP54 with the vent plug open and IP65 or NEMA 4 when the plug is closed, so dust and wash-down jets are handled but continuous immersion is not.

1/4 in NPT bottom connection

The process connection is a 1/4 inch male NPT thread located at the bottom of the case. This standard fitting works with common pipe and adapter hardware, yet the fixed bottom entry limits panel layouts that require a rear or lower-back mount. No other connection sizes or orientations are offered on this model.

Questions about this item

Will the 1/4 in NPT male connection on this 251009 gauge thread directly into the existing port on my older pump?

The gauge uses a 1/4 in NPT male process connection, so it will thread into any matching female NPT port; verify the port size and thread standard on your pump before installing.

How can I confirm the 251009 is reading within its +/- 1.5 percent accuracy after I mount it?

Apply a known reference pressure from a calibrated source and compare the reading on the 2 1/2 in dial; the needle should stay within 1.5 percent of full scale across the 0 to 1,500 psi range.

Does the 251009 ship with the glycerine fill installed, or do I need to purchase liquid separately for the field-fillable case?

The case is field fillable and vibration resistance is listed as liquid-filled, so the damping fluid is not pre-installed; you must buy the appropriate fill fluid separately.
