Ashcroft 93696XLL Pressure Gauge 4.5 in Dial 0-100 Psi

Product Description

The ASHCROFT 93696XLL is an analog pressure gauge built for accurate pressure monitoring in demanding trade applications. It features a 4.5-inch dial for easy readout from a distance, a 1/4-inch rear threaded connection, and a rear flange mount configuration suited for panel or wall installations. The wetted parts are bronze, making it compatible with a wide range of fluids and gases. The aluminum case keeps weight low at 2.5 pounds while providing solid protection. Accuracy is rated at 0.5 percent of full scale across a 0 to 100 psi range, meeting the needs of HVAC, plumbing, and industrial service professionals who require reliable, readable pressure indication.

This gauge is well suited for use in residential and light commercial HVAC systems, plumbing pressure testing, compressed air lines, and general fluid system monitoring. The rear flange mount allows the gauge to be secured flush to a panel or bulkhead, keeping the face visible while protecting the connection from stress. The no-fill analog design simplifies installation and eliminates liquid-fill compatibility concerns in installations where vibration is not a primary factor. Technicians working on boilers, water supply systems, refrigeration circuits, and compressed gas lines will find this gauge a practical choice.

Key Features

• 4.5-inch analog dial for clear, distance-readable pressure indication
• 0 to 100 psi pressure range with 0.5 percent of full-scale accuracy
• Bronze wetted parts suitable for compatibility with a broad range of media
• Aluminum case construction for reduced weight and corrosion resistance
• Rear flange mount design supports panel and bulkhead installations
• No liquid fill — straightforward installation with no fill-fluid handling required

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for residential and commercial systems requiring a 4.5-inch dial, 1/4-inch rear-threaded connection, and rear flange mount in the 0 to 100 psi range.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or qualified mechanical contractor. Shut off and depressurize the system completely before removing any existing gauge or fitting. Apply thread sealant appropriate for the system media to the 1/4-inch male threads before installation and tighten to hand-tight plus a quarter turn — avoid over-tightening, which can crack the socket or distort the bourdon tube. Verify there are no leaks at operating pressure before returning the system to service.
