Ashcroft 93751XLL Pressure Gauge 4.5 in Dial 0-160 Psi

Product Description

The ASHCROFT 93751XLL is an analog pressure gauge built for accurate, reliable pressure measurement in demanding trade applications. It features a 4.5-inch dial for easy readability at a distance, a pressure range of 0 to 160 psi, and a rear flange mount configuration for panel or wall installations. Accuracy is rated at 0.5 percent of scale, meeting the requirements of most commercial and industrial monitoring applications. The wetted parts are stainless steel, providing corrosion resistance against a wide range of media. The case is aluminum, keeping overall weight low without sacrificing durability. This gauge ships dry with no liquid fill.

This gauge is suited for use in HVAC systems, plumbing installations, industrial process lines, and mechanical rooms where panel-mounted pressure monitoring is required. The rear flange mount allows direct surface or panel mounting with the connection exiting from the back, keeping the face clean and the installation compact. The 1/4-inch threaded connection is a common size for a wide variety of piping and fitting configurations. Licensed HVAC technicians, plumbers, and industrial mechanics typically install this style of gauge on air, gas, water, and compatible fluid systems.

Compatibility

Designed as an OEM-style replacement or direct-install analog pressure gauge suitable for residential and commercial HVAC, plumbing, and light industrial pressure monitoring applications using a 1/4-inch threaded rear connection.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanic. Shut off and depressurize the system completely before removing any existing gauge or making new connections. Apply thread sealant or PTFE tape to the 1/4-inch male threads per local code and manufacturer practice. Do not overtighten the connection, as this can crack the socket or distort the Bourdon tube internally.
