Ashcroft 61379S04LXLL300 Pressure Gauge 0-300 Psi

Product Description

The ASHCROFT 61379S04LXLL300 is a process industrial pressure gauge built for demanding trade and industrial applications. It features a 6-inch analog dial with a 0 to 300 psi range, providing clear, at-a-glance pressure readings in high-visibility environments. The case is constructed from aluminum, and all wetted parts are stainless steel, making it suitable for use with corrosive or aggressive media. Accuracy is rated at 0.5% of scale, which meets the requirements of most industrial process monitoring applications. The gauge connects via a 1/2-inch MNPT lower-mount fitting and requires no liquid fill. It is installed by licensed plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals.

This gauge is designed for process and industrial installations where a reliable, dry-type pressure indicator is required. The lower-mount configuration suits panel-mounted or pipe-mounted installations where the process connection enters from the bottom. The IP66 and NEMA 4X ratings make it appropriate for outdoor or wash-down environments. The glass lens and aluminum case keep weight manageable at 3.13 pounds while maintaining durability under continuous service. Typical applications include compressed air systems, hydraulic lines, water systems, and general process piping in commercial and industrial facilities.

Compatibility

Designed as an OEM-style process pressure gauge compatible with 1/2-inch MNPT lower-mount installations in industrial process piping, compressed air, hydraulic, and water systems requiring a 0 to 300 psi dry-type indicator.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or industrial maintenance technician following applicable local codes and manufacturer guidelines. Depressurize and isolate the line completely before installing or removing the gauge. Use an appropriate thread sealant on the MNPT threads and avoid over-tightening, which can damage the gauge socket. Verify that the process media is compatible with stainless steel wetted parts before placing the gauge in service.
