Ashcroft 93703XLL Pressure Gauge 4.5 in Dial 0-1000 Psi

Product Description

The ASHCROFT 93703XLL is an analog pressure gauge designed for industrial and mechanical service applications requiring reliable, accurate pressure measurement. With a 4.5-inch dial, this gauge delivers clear readability in the field without the need for magnification or close-up inspection. It covers a pressure range of 0 to 1000 psi with an accuracy of 0.5 percent of scale, making it well-suited for monitoring pumps, compressors, piping systems, and process equipment. The aluminum case keeps overall weight low while offering corrosion resistance in many environments. Bronze wetted parts provide durability and compatibility with a broad range of common media. This gauge is installed by licensed plumbers, pipefitters, HVAC technicians, and mechanical contractors.

The 93703XLL is configured for rear flange mount with a 1/4-inch thread connection, positioning it for panel or bulkhead installations where the gauge face needs to sit flush against a surface. The dry, no-fill design means there is no liquid dampening, which is appropriate for steady-state pressure monitoring in low-vibration environments. This gauge fits residential and light commercial applications as well as industrial settings where a reliable analog readout is preferred over digital instrumentation. The rear entry connection simplifies integration into existing panel cutouts and manifold assemblies.

Key Features

• 4.5-inch analog dial for clear, at-a-glance pressure readings
• 0 to 1000 psi pressure range with 0.5 percent of scale accuracy
• Rear flange mount configuration for panel and bulkhead installations
• 1/4-inch threaded connection for direct fitting to standard ports
• Aluminum case reduces weight while resisting corrosion in typical service environments
• Bronze wetted parts provide broad media compatibility and long service life
• Dry, no-fill design suited for stable, low-vibration pressure monitoring

Compatibility

Designed as an OEM-style or replacement analog pressure gauge for pump systems, compressors, piping manifolds, and process equipment requiring a rear flange mount, 1/4-inch connection, and a 0 to 1000 psi measurement range.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or mechanical technician in accordance with applicable local and national codes. Depressurize the system fully before removing any existing gauge or connecting the new gauge to the port. Use appropriate thread sealant on the 1/4-inch connection and avoid over-tightening, which can damage the brass socket or gauge internals. In high-vibration applications, consider a liquid-filled gauge or a snubber fitting to protect gauge accuracy and longevity.
