Ashcroft 601379S04LXLL30 Pressure Gauge 0-30 Psi

Product Description

The ASHCROFT 601379S04LXLL30 is a process industrial pressure gauge designed for demanding industrial and mechanical applications. It features a 6-inch analog dial with a 0 to 30 psi range and delivers 0.5% of scale accuracy, making it suitable for process monitoring where reliable readings are critical. The gauge is dry (no liquid fill) and uses a lower-mount, 1/2-inch MNPT connection for direct inline installation. Stainless steel wetted parts resist corrosion in contact with process media, while the aluminum case keeps overall weight manageable. Licensed HVAC technicians, plumbers, and industrial mechanics routinely specify this gauge for pressure monitoring on piping systems, compressors, and process equipment.

This gauge is appropriate for both commercial and light industrial process applications where a large, easy-to-read dial is required. The 6-inch dial diameter improves readability at a distance, and the glass lens provides a clear view of the analog indicator. The lower-mount configuration suits panel-mounted or pipe-stub installations where the connection enters from the bottom of the gauge. It is a non-liquid-filled unit, which simplifies installation and eliminates concerns about filler fluid compatibility with the process environment.

Key Features

• 6-inch analog dial with 0 to 30 psi range for broad, clear process pressure monitoring
• 0.5% of scale accuracy for reliable, repeatable readings
• Stainless steel wetted parts for corrosion resistance in contact with process media
• Aluminum case reduces weight while maintaining structural integrity
• Lower-mount 1/2-inch MNPT connection for straightforward inline or panel installation
• Glass lens for clear dial visibility; rated IP66 and NEMA 4X for washdown and weather exposure
• CRN certified and meets IP66/NEMA 4X standards

Compatibility

Designed as an OEM-style or replacement process pressure gauge for industrial piping, compressor systems, and process equipment requiring a lower-mount, 1/2-inch MNPT connection with a 0 to 30 psi range. Part of the Ashcroft 1379 Series.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified industrial mechanic. Depressurize and isolate the process line fully before removing any existing gauge or fitting the new unit. Apply thread sealant appropriate for the process media to the 1/2-inch MNPT threads before installation. Verify that the process media is compatible with stainless steel wetted parts and aluminum case materials before commissioning.
