Ashcroft 61379S04LXLL800 Pressure Gauge 6 in 800 Psi

Product Description

The ASHCROFT 61379S04LXLL800 is a 6-inch analog pressure gauge designed for industrial and mechanical service applications where reliable pressure monitoring is required. It features a lower-mount, 1/2-inch threaded connection and reads from 0 to 800 psi with an accuracy of 0.5 percent of scale. The aluminum case keeps weight low while the stainless steel wetted parts resist corrosion from a wide range of process media. This gauge is non-liquid-filled, making it well suited for clean-air, gas, and compatible fluid systems where a dry-dial instrument is specified. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers.

This gauge is commonly used in commercial HVAC, refrigeration, compressed air, water distribution, and industrial process piping applications. The 6-inch dial provides easy readability at a distance, which is valuable on mechanical room equipment and rooftop units. The lower-mount configuration allows direct inline or panel-mounted installation on vertical pipe runs. It is appropriate for residential and light commercial mechanical systems as well as heavier industrial service where a dry-case gauge meets the pressure range requirement.

Key Features

• 6-inch analog dial for clear, at-a-glance pressure readings
• 0 to 800 psi range with 0.5 percent of scale accuracy
• 1/2-inch lower-mount threaded connection for direct pipe installation
• Stainless steel wetted parts resist corrosion from process fluids
• Aluminum case reduces overall weight at 3.13 pounds
• Non-liquid-filled design suited for dry-service environments

Compatibility

Designed as an OEM-style and aftermarket replacement pressure gauge for industrial, commercial HVAC, compressed air, and process piping systems requiring a 6-inch dry-dial gauge with a 1/2-inch lower-mount connection and a 0 to 800 psi range.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Always depressurize the system completely before removing or installing any pressure gauge. Apply thread sealant appropriate for the process media to the 1/2-inch NPT threads, and tighten to the fitting manufacturer's recommendation using a wrench on the gauge hex — never torque through the case body. Verify the system pressure range does not exceed the gauge full-scale rating before returning the system to service.
