Choose inch tube OD, NPT end, material and service range from the published series; specify calibration where relevant.
Application & RFQ details
RFQ: measuring range in psi or deg F, process connection, wetted material, accuracy and vibration/pulsation conditions. Confirm dimensions and any hazardous-area requirement.
Standards & documents
Match gauge response time and surge conditions; a snubber is not an overpressure relief device. NPT per ASME B1.20.1.
