Ashcroft 93115XLL Pressure Gauge 0-600 Psi 4.5 in Dial

Product Description

The ASHCROFT 93115XLL is a process industrial pressure gauge designed for demanding commercial and industrial fluid systems. It features a 4.5-inch analog dial with a measurement range of 0 to 600 psi and delivers 0.5% of scale accuracy, making it suitable for applications where reliable pressure readings are critical. The aluminum case houses a glass lens for clear dial visibility, while bronze wetted parts provide solid corrosion resistance against common process media. The 1/4-inch MNPT center back mount connection simplifies installation in tight panel or bulkhead configurations. Licensed HVAC technicians, plumbers, and industrial service techs regularly specify this gauge for permanent system monitoring.

This gauge is suited for process piping, HVAC hydronic systems, compressed air distribution, and general industrial pressure monitoring in both commercial and light industrial environments. The no-fill design keeps installation straightforward without the complications of liquid-filled gauge maintenance. Its center back mount orientation makes it a standard choice for panel-mounted instrumentation where front-facing dial readability is required from a fixed vantage point.

Compatibility

Designed as an OEM-style replacement or direct-fit gauge for process industrial pressure monitoring installations requiring a 1/4-inch MNPT center back mount connection and a 4.5-inch dial format.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable IPC or IFGC codes for the system type. Isolate and depressurize the system completely before removing any existing gauge or fitting. Apply appropriate thread sealant to the MNPT connection and hand-tighten before final torque with a wrench; avoid over-tightening, which can crack the case or damage threads. Verify the system pressure range does not exceed the 600 psi maximum rating of this gauge before returning the system to service.
