Ashcroft 451379SS02LXLL- Pressure Gauge 1500 Psi 4.5 in

Product Description

The ASHCROFT 451379SS02LXLL- is a process industrial pressure gauge designed for demanding industrial and mechanical system monitoring applications. It features a 4.5-inch analog dial with a 0 to 1,500 psi range, giving technicians a clear, wide-view readout in high-pressure environments. The gauge is built with an aluminum case and stainless steel wetted parts, making it well suited for use with corrosive or high-purity media. Accuracy is rated at 0.5 percent of scale. The glass lens provides durability against splashing and particulate exposure. Licensed trades and industrial service technicians install this gauge as part of permanent instrumentation packages.

This gauge fits process piping, compressed air systems, hydraulic lines, and water treatment installations where a reliable lower-mount connection is required. The 1/4-inch MNPT lower-mount connection simplifies installation into standard process tees, manifolds, and isolation valves. Its CRN certification and IP66/NEMA 4X rating make it appropriate for Canadian-registered pressure vessels and outdoor or wash-down environments. This is a dry, no-fill gauge intended for applications where liquid-filled dampening is not required.

Key Features

• 4.5-inch analog dial with 0 to 1,500 psi range for clear high-pressure readout
• Stainless steel wetted parts resist corrosion from aggressive media
• Aluminum case keeps overall weight low at 2.5 pounds
• 0.5 percent of scale accuracy suits precision process monitoring
• IP66/NEMA 4X rated for outdoor, wet, and wash-down installations
• CRN certified for Canadian pressure vessel registration requirements
• Dry no-fill design simplifies service and disposal

Compatibility

Designed as an OEM-style process gauge compatible with standard 1/4-inch MNPT lower-mount port fittings found on industrial process lines, compressed air systems, and hydraulic manifolds requiring a 4.5-inch dial instrument rated to 1,500 psi.

Installation Notes

Installation should be performed by a qualified technician or licensed trades professional. Isolate and depressurize the system fully before removing or installing any pressure gauge. Apply thread sealant appropriate for the media type to the MNPT threads and tighten to fitting manufacturer specifications using a proper wrench on the gauge hex body — do not apply torque to the dial case. Verify the gauge range is appropriate for the system operating pressure before returning the line to service.
