Ashcroft 451379S02LXLL2K Pressure Gauge 4.5 in 0-2000 Psi

Product Description

The ASHCROFT 451379S02LXLL2K is an analog pressure gauge built for demanding industrial and mechanical service applications. It features a 4.5-inch dial for easy readout at a distance, a lower-mount 0.25-inch threaded connection, and stainless steel wetted parts that resist corrosion in harsh media. The gauge measures pressure from 0 to 2000 psi with an accuracy of 0.5 percent of scale. The aluminum case keeps weight low while providing solid protection. This is a dry (non-liquid-filled) gauge, suited for systems where vibration is not excessive and ambient contamination of the movement is not a concern. Licensed technicians and pipefitters in HVAC, plumbing, and industrial service rely on gauges of this type for system commissioning, pressure testing, and monitoring.

This gauge is appropriate for residential and commercial mechanical systems requiring a reliable, locally read pressure indication. Lower-mount connection allows direct inline mounting on manifolds, pipe tees, pressure test ports, and equipment service ports. The 0 to 2000 psi range covers a wide variety of high-pressure hydraulic, compressed air, steam, gas, and water service applications. The stainless steel wetted components make it compatible with mildly corrosive process media as well as standard air and water systems.

Key Features

• 4.5-inch analog dial for clear, high-visibility pressure readout
• 0 to 2000 psi range with 0.5 percent of scale accuracy
• Stainless steel wetted parts for corrosion resistance in wet or aggressive media
• Lower-mount 0.25-inch threaded connection for direct pipe or manifold installation
• Aluminum case construction reduces overall weight
• Dry (no-fill) design suits low-vibration service environments

Compatibility

Designed as an OEM-style and aftermarket replacement pressure gauge for compressed air, hydraulic, gas, and water systems requiring a lower-mount, 0.25-inch threaded, 4.5-inch dial analog gauge rated to 2000 psi.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the system completely before removing any existing gauge or fittings. Apply appropriate thread sealant or PTFE tape to the male threads per the applicable plumbing or mechanical code, and tighten to the fitting manufacturer recommendation using a wrench on the gauge hex — do not apply torque through the case body. For high-vibration applications, consider a liquid-filled gauge to extend service life.
