Ashcroft 61379S02LXLL400 Pressure Gauge 6 in 400 Psi

Product Description

The ASHCROFT 61379S02LXLL400 is an analog pressure gauge built for trade and industrial service applications where accurate, reliable pressure readings are required. It features a 6-inch dial face for easy at-a-glance readout and a 1/4-inch lower-mount connection for direct inline or panel installation. The pressure range spans 0 to 400 PSI with an accuracy rating of 0.5 percent of full scale. The aluminum case keeps weight manageable at 3.13 pounds, while stainless steel wetted parts resist corrosion in demanding fluid and gas service environments. This gauge is a dry, no-fill unit suited for HVAC, plumbing, and general mechanical systems where vibration dampening from liquid fill is not required.

This gauge is appropriate for residential and commercial mechanical systems where monitoring line pressure, system pressure, or test pressure is part of routine service or installation. The lower-mount configuration allows direct connection to a pipe tee, manifold, or test port without additional fittings in most standard setups. HVAC technicians, plumbers, and pipefitters commonly install this type of gauge on boilers, compressed air lines, hydronic heating systems, chilled water loops, and general fluid distribution piping. The 6-inch dial size makes it practical for both panel-mounted and field service applications where readability at a distance matters.

Key Features

• 6-inch analog dial face for clear, at-a-distance pressure readings
• 0 to 400 PSI pressure range suitable for a wide range of mechanical systems
• 0.5 percent of full-scale accuracy for precise pressure monitoring
• Stainless steel wetted parts for corrosion resistance in fluid and gas service
• Aluminum case construction reduces overall weight without sacrificing durability
• Dry, no-fill design simplifies installation and eliminates liquid fill maintenance
• 1/4-inch lower-mount connection for direct pipe or manifold installation

Compatibility

Designed as an OEM-style or replacement analog pressure gauge for residential and commercial HVAC, plumbing, and mechanical piping systems requiring a 1/4-inch lower-mount connection and a 0 to 400 PSI range.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or HVAC technician. Isolate and depressurize the system fully before removing any existing gauge or fitting. Apply appropriate thread sealant to the 1/4-inch NPT connection per local plumbing and mechanical codes. Do not overtighten the gauge connection, as this can damage the bourdon tube or case threads.
