Ashcroft 93748XLL Pressure Gauge 0-30 Psi 4.5 in Dial

Product Description

The ASHCROFT 93748XLL is a process industrial pressure gauge designed for demanding industrial and commercial applications where accurate, reliable pressure monitoring is required. The gauge features a 4.5-inch analog dial with a 0 to 30 psi range and an accuracy rating of 0.5% of scale. The aluminum case provides a lightweight yet durable housing, while stainless steel wetted parts deliver corrosion resistance when exposed to process media. The glass lens and dry (no-fill) configuration make this gauge straightforward to read and maintain in the field. Licensed plumbers, pipefitters, and HVAC service technicians are the primary installers for this type of instrument.

The 93748XLL is suited for process piping systems, HVAC mechanical rooms, water treatment lines, and light industrial process monitoring where low-range pressure readings up to 30 psi must be observed at a panel or manifold. The rear flange mount configuration allows direct panel or wall mounting with the dial face oriented outward for easy reading. The 1/4-inch MNPT thread connection fits standard pipe fittings and instrumentation ports commonly found in process and mechanical systems. This gauge is appropriate for both new installations and service replacements in industrial and commercial environments.

Key Features

• 4.5-inch analog dial for clear, at-a-distance reading in process environments
• 0 to 30 psi pressure range with 0.5% of scale accuracy
• Stainless steel wetted parts for corrosion resistance in process media contact
• Aluminum case construction — lightweight and durable
• Rear flange mount for panel or wall installation with forward-facing dial
• Dry (no liquid fill) design simplifies handling and installation
• Meets CRN and IP66/NEMA 4X standards for industrial and wet-location use

Compatibility

Designed as an OEM-style process pressure gauge for industrial and commercial piping systems using standard 1/4-inch MNPT instrumentation ports. Part of the ASHCROFT Series 1379.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified instrumentation technician following applicable local codes and ASME B40.100 gauge installation guidelines. Isolate and fully depressurize the system before removing any existing gauge or installing this unit. Apply thread sealant appropriate for the process media to the MNPT threads — do not overtighten, as this can damage the gauge socket or process connection. Verify the process pressure does not exceed the 30 psi maximum range of this gauge before placing the system back in service.
