Ashcroft 601379A04LXLL60 Pressure Gauge 6 in 0-60 Psi

Product Description

The ASHCROFT 601379A04LXLL60 is a 6-inch dial analog pressure gauge designed for direct lower-mount installation via a 1/2-inch NPT connection. It measures pressure from 0 to 60 psi and delivers 0.5% of scale accuracy, making it suitable for applications where reliable pressure readings are critical. The aluminum case keeps weight down while the bronze wetted parts provide corrosion resistance in contact with measured media. This is a dry-fill (no liquid-filled) gauge, weighing 3.13 pounds. It is installed by licensed plumbers, HVAC technicians, and mechanical contractors on piping, compressed air systems, water distribution lines, and other process or building utility systems.

This gauge is suited for commercial and industrial installations where a large, easy-to-read 6-inch dial is needed at a panel, manifold, or pipe riser. The lower mount configuration allows the gauge to sit upright when threaded directly into a bottom-entry port or tee fitting. It is commonly found on boiler systems, chiller circuits, compressed air headers, and water supply lines in both new construction and retrofit service. No liquid fill means reduced risk of leakage from the case in installations where glycerin or silicone fill is not required or preferred.

Key Features

• 6-inch analog dial for high-visibility pressure reading at distance
• 0 to 60 psi pressure range with 0.5% of scale accuracy
• Lower mount configuration for direct vertical pipe entry
• 1/2-inch NPT threaded connection
• Aluminum case construction reduces overall weight
• Bronze wetted parts resist corrosion from common water and air media
• Dry fill design eliminates liquid-fill leak concerns

Compatibility

Designed as a direct-replacement or new-installation analog pressure gauge for lower-mount NPT pipe connections on commercial and residential HVAC, plumbing, and compressed air systems requiring a 6-inch dial and 0 to 60 psi range.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor. Depressurize and isolate the system fully before removing an existing gauge or threading in a new one. Apply appropriate thread sealant or PTFE tape to the NPT threads and tighten to the fitting manufacturer's specification using a wrench on the gauge's hex fitting, not the case or dial. Avoid over-tightening, which can damage the bourdon tube or case threads.
