Ashcroft 601379S4LXLL20K Pressure Gauge 6 Inch 20000 Psi

Product Description

The ASHCROFT 601379S4LXLL20K is an analog pressure gauge built for industrial and mechanical service applications requiring high-range pressure measurement up to 20000 psi. The gauge features a 6-inch dial face for clear readability at a distance, a lower-mount 1/2-inch threaded connection, and an aluminum case. Wetted parts are stainless steel, making it suitable for use with corrosive media or high-purity process lines. Accuracy is rated at 0.5 percent of scale. This gauge is a dry (no-fill) unit, meaning it contains no liquid dampening fluid, keeping it lightweight and straightforward to install in low-vibration environments.

This gauge is used in high-pressure industrial, hydraulic, and process piping systems where a large-dial readout is required. The lower-mount configuration positions the process connection at the 6 o'clock position on the gauge body, which is standard for panel-mount or pipe-mounted installations on vertical runs. The 0 to 20000 psi range makes it appropriate for hydraulic test benches, high-pressure water systems, gas cylinder manifolds, and similar demanding service points. Licensed plumbers, pipefitters, and mechanical contractors are the typical installers in commercial and industrial settings.

Key Features

• 6-inch analog dial for clear, long-distance readability
• 0 to 20000 psi pressure range for high-pressure service
• Stainless steel wetted parts for compatibility with corrosive or high-purity media
• Aluminum case for reduced weight compared to brass or stainless housings
• 0.5 percent of scale accuracy for reliable measurement
• Dry (no-fill) design suited for low-vibration installations
• Lower-mount 1/2-inch threaded connection for panel and pipe applications

Compatibility

Designed as an OEM-style analog pressure gauge for lower-mount installations in high-pressure industrial and mechanical piping systems requiring a 1/2-inch threaded process connection.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or qualified mechanical technician. Isolate and fully depressurize the system before removing any existing gauge or installing this unit. Apply an appropriate thread sealant to the 1/2-inch male threads in accordance with applicable codes such as the IPC or ASME B31.3 for process piping. Do not over-torque the threaded connection into the process port, as this can damage the bourdon tube or crack the socket fitting.
