Industrial pressure gauge 0–30 psi
The Ashcroft 251009 is a dry industrial pressure gauge built for measuring fluid or gas pressure up to 30 psi. It suits plant engineers, maintenance technicians and OEM integrators who need a reliable panel or inline instrument for process monitoring.
304 stainless case with 1/4 NPT bottom mount
A 2 1/2 in dial sits inside a 304 stainless steel case rated IP54 when the vent plug is open and IP65 when closed, also meeting NEMA 4 sealed. The polycarbonate lens resists impact and the 1/4 in male NPT bottom connection threads directly into standard process ports without adapters.
Accuracy and environmental performance
Accuracy is specified at ±1.0 percent of span across the 0–30 psi range. The PLUS! Performance dampening feature steadies the pointer against vibration and pressure pulsation. The dry, field-non-fillable design eliminates leak risk and keeps the gauge light for bracket or direct mounting.

Questions about this item
What does the IP54 and IP65 rating mean for the 1/4 NPT connection?
The gauge is IP54 rated with the vent plug open and IP65 rated with the plug closed, protecting the 1/4 NPT connection from dust and water jets when sealed.
Will the 2 1/2 inch dial and 4.500 inch length fit my panel cutout?
The nominal dial size is 2 1/2 inches with an overall length of 4.500 inches and width of 3.200 inches, requiring a panel cutout that accommodates these dimensions for bottom mounting.
How do I install the PLUS! Performance dampening feature correctly?
Install the gauge with the 1/4 NPT male connection at the bottom; the dry PLUS! Performance dampening is factory-set and requires no field filling, but ensure the vent plug is positioned correctly for your IP rating needs.
