Ashcroft 61379S4LXLL1.5K Pressure Gauge 6 in 1500 Psi

Product Description

The ASHCROFT 61379S4LXLL1.5K is a 6-inch analog pressure gauge designed for industrial and mechanical system monitoring applications. It features a lower-mount, 1/2-inch threaded connection and covers a pressure range of 0 to 1500 psi. The wetted parts are stainless steel for corrosion resistance in demanding fluid and gas service environments. The case is aluminum, keeping overall weight manageable at 3.13 pounds. Accuracy is rated at 0.5% of scale, making this gauge suitable for applications where precise pressure readings are required. It ships as a dry (no-fill) gauge without liquid dampening.

This gauge is suited for use in commercial and industrial plumbing, HVAC, and process piping systems where reliable pressure monitoring at higher ranges is needed. The 6-inch dial provides a large, easy-to-read face from a distance, which is practical in mechanical rooms or equipment areas. The lower-mount configuration positions the connection port at the bottom of the case, a common arrangement for panel-mounted or pipe-tee installations. Licensed plumbers, pipefitters, and HVAC mechanics typically specify this type of gauge for boiler systems, compressed air lines, water supply headers, and hydraulic circuits operating up to 1500 psi.

Key Features

• 6-inch analog dial for clear, at-a-distance pressure reading
• 0 to 1500 psi pressure range suitable for high-pressure system monitoring
• Stainless steel wetted parts resist corrosion in water, steam, and chemical service
• Aluminum case reduces overall weight while providing durable housing
• 0.5% of scale accuracy for reliable, repeatable readings
• Dry (no liquid fill) construction for standard ambient-temperature applications

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for industrial and commercial mechanical systems requiring a 6-inch lower-mount analog gauge with a 1/2-inch threaded process connection rated to 1500 psi.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC mechanic in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Isolate and fully depressurize the system before removing an existing gauge or making a new connection. Use appropriate thread sealant on the 1/2-inch NPT connection and tighten to the fitting manufacturer's specification using a wrench on the gauge socket, not on the case or dial. Do not exceed the gauge's rated pressure range during system commissioning or pressure testing.
