Ashcroft 93108XLL Pressure Gauge 0-30 Psi 4.5 in Dial

Product Description

The ASHCROFT 93108XLL is a process industrial pressure gauge designed for demanding commercial and industrial service environments. It features a 4.5-inch analog dial with a 0 to 30 psi range and delivers an accuracy of 0.5 percent of scale, making it suitable for applications where reliable, repeatable readings are required. The case is constructed from aluminum for corrosion resistance and reduced weight, while all wetted internal parts are bronze to handle a broad range of media. The glass lens provides clear readability under typical field conditions. This gauge mounts via a 1/4-inch MNPT center back connection and ships dry with no liquid fill.

This gauge is commonly installed in process piping systems, HVAC mechanical rooms, compressed air lines, water distribution panels, and light industrial fluid systems where moderate pressure monitoring is needed. The center back mount configuration suits panel cutout and pipe stub installations where face-forward readability is the priority. Licensed plumbers, HVAC technicians, and process pipefitters are the typical trades specifying and installing this type of gauge.

Compatibility

Designed as an OEM-style replacement or direct-install process pressure gauge for residential, commercial, and light industrial piping and mechanical systems requiring a 1/4-inch MNPT center back mount connection with a 4.5-inch dial.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Shut off system pressure and depressurize the line fully before removing any existing gauge or installing this unit. Use an appropriate thread sealant on the MNPT connection and tighten to fitting manufacturer specifications — avoid over-torquing the aluminum case. Verify the installed gauge range is appropriate for the system operating pressure before returning the system to service.
