Ashcroft 61379S04LXLL400 Pressure Gauge 6 in 400 Psi

Product Description

The ASHCROFT 61379S04LXLL400 is a 6-inch analog pressure gauge designed for industrial and mechanical service applications where accurate pressure monitoring is required. The gauge features a lower-mount 1/2-inch NPT connection, an aluminum case, and stainless steel wetted parts for corrosion resistance in contact with process media. It reads from 0 to 400 psi with an accuracy of 0.5 percent of scale. No liquid fill is used, making it straightforward to install and service. Plumbers, pipefitters, HVAC technicians, and industrial service professionals install this type of gauge on systems where a clear, reliable pressure reading is critical to safe operation.

This gauge is suited for use on water lines, compressed air systems, HVAC chiller and hydronic loops, process piping, and other systems operating within the 0 to 400 psi range. The 6-inch dial provides a large, easy-to-read analog display, which is practical in mechanical rooms and equipment areas where gauges are read from a distance. The lower-mount configuration allows for direct pipe or manifold connection with a vertical dial face orientation.

Key Features

• 6-inch analog dial for high visibility in mechanical and process environments
• 0 to 400 psi pressure range with 0.5 percent of scale accuracy
• Stainless steel wetted parts resist corrosion from process media
• Aluminum case provides lightweight, durable housing
• Lower-mount 1/2-inch NPT connection for direct pipe or manifold installation
• Non-liquid-filled construction simplifies installation and maintenance

Compatibility

Designed as an OEM-style replacement or new-installation gauge for systems requiring a 6-inch dial, lower-mount, 1/2-inch NPT analog pressure gauge rated to 400 psi with stainless steel wetted parts.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the system completely before removing an existing gauge or installing a new one. Use appropriate thread sealant or PTFE tape on the NPT threads and tighten to the fitting manufacturer recommendation without over-torquing the gauge socket. Verify the system pressure range falls within the 0 to 400 psi rated span before returning the system to service.
