Ashcroft 93695XLL Pressure Gauge 4.5 in Rear Flange Mount

Product Description

The ASHCROFT 93695XLL is an analog pressure gauge designed for industrial and mechanical system monitoring. The gauge features a 4.5-inch dial with a rear flange mount configuration, making it suited for panel or bulkhead installations where a clean front face is required. The aluminum case houses a bronze wetted parts assembly, delivering corrosion-resistant contact with measured media. Accuracy is rated at 0.5 percent of scale across a pressure range of 0 to 60 psi. This is a dry (non-liquid-filled) gauge intended for stable pressure monitoring applications.

This gauge is used in HVAC, plumbing, and general mechanical systems where pressure measurement at a panel or remote mounting point is required. The rear flange mount design allows secure wall or panel installation with the connection plumbing running behind the surface. The 1/4 inch threaded connection is a common industry-standard size for instrumentation and control line hookups. Licensed HVAC technicians, plumbers, and industrial service professionals are the typical end users for this type of instrument.

Key Features

• 4.5-inch analog dial for clear, at-a-distance pressure readings
• Rear flange mount for panel and bulkhead installations
• 0.5 percent of scale accuracy across the full 0 to 60 psi range
• Bronze wetted parts resist corrosion from measured media
• Lightweight aluminum case construction
• Dry gauge design — no liquid fill, suitable for stable-pressure environments

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for residential and commercial HVAC, plumbing, and mechanical systems requiring a 1/4 inch rear-entry connection with rear flange mounting.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or qualified instrumentation technician. Isolate and depressurize the system completely before removing an existing gauge or making new connections. Apply appropriate thread sealant to the 1/4 inch connection per the system fluid or gas compatibility requirements. Do not overtighten the threaded connection, as this can damage the gauge socket or the bronze wetted parts.
