Ashcroft 93749XLL Pressure Gauge 4.5 in Dial 0-60 Psi Rear Flange

Product Description

The ASHCROFT 93749XLL is an analog pressure gauge engineered for industrial and mechanical system applications where reliable pressure indication is critical. The gauge features a 4.5-inch diameter dial for clear readability from a distance, a stainless steel wetted parts construction for corrosion resistance in demanding media, and an aluminum case that keeps weight low. It covers a pressure range of 0 to 60 PSI with an accuracy of 0.5 percent of scale, making it suitable for applications that require consistent, repeatable readings. This is a dry (no-fill) gauge intended for installation by licensed plumbers, HVAC technicians, pipefitters, or industrial maintenance professionals.

This gauge is designed for use in piping systems where rear flange mounting is required, including mechanical rooms, process piping, and HVAC hydronic systems. The rear flange mount allows the gauge to be panel- or wall-mounted with the process connection entering from the back, keeping the installation clean and secure. The 0 to 60 PSI range suits low-to-medium pressure monitoring duties in water, gas, and compatible fluid systems where stainless steel wetted materials are appropriate for the media being measured.

Key Features

• 4.5-inch analog dial for clear, at-a-distance pressure readings
• 0 to 60 PSI pressure range with 0.5 percent of scale accuracy
• Stainless steel wetted parts provide corrosion resistance in wet or chemical-exposed environments
• Aluminum case reduces overall weight while maintaining structural integrity
• Rear flange mount design supports panel and wall installations with a clean profile
• Dry (no-fill) gauge suitable for non-pulsating, non-vibration-heavy applications

Compatibility

Designed as an OEM-style or aftermarket replacement pressure gauge for piping, HVAC hydronic, and industrial process systems requiring a rear flange mount configuration with a 0 to 60 PSI range and a 4.5-inch dial face.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician in accordance with applicable local codes and system specifications. Isolate and depressurize the system fully before removing or installing the gauge. Use appropriate thread sealant on the 0.25-inch threaded connection and avoid overtightening, which can damage the gauge socket or case. Because this is a dry gauge, avoid installing it in high-vibration or heavy-pulsation service without an appropriate snubber or isolator.
