Ashcroft 93110XLL Pressure Gauge 4.5 in 0-100 Psi Back Mount

Product Description

The ASHCROFT 93110XLL is an analog pressure gauge designed for industrial and mechanical system monitoring applications. It features a 4.5-inch aluminum case dial with bronze wetted parts and delivers an accuracy rating of 0.5 percent of scale across a 0 to 100 psi range. The center back mount configuration allows direct in-line installation into piping systems using a 1/4-inch threaded connection. This gauge is a dry (no-fill) unit, making it suitable for environments where liquid-filled gauges are not required. It is installed by licensed plumbers, HVAC technicians, pipefitters, and mechanical contractors who need reliable pressure indication on water, air, gas, or compatible fluid systems.

The 93110XLL is suited for residential and light commercial applications where a mid-size, panel-readable pressure gauge is needed. Typical installations include boiler systems, compressed air lines, water supply monitoring, and hydronic heating loops. The center back mount orientation is well matched to panel-mounted or manifold-mounted installations where the gauge face must be flush and forward-facing. The 1/4-inch threaded port is a common connection size found across a wide range of system service ports and manifold blocks.

Key Features

• 4.5-inch dial diameter for clear, at-a-distance pressure reading
• 0 to 100 psi pressure range with 0.5 percent of scale accuracy
• Aluminum case construction reduces overall weight
• Bronze wetted parts provide corrosion resistance in water and air service
• Center back mount with 1/4-inch thread for direct inline panel installation
• Dry (no-fill) design eliminates liquid fill maintenance concerns

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for residential and light commercial piping, HVAC, and compressed air systems requiring a 1/4-inch center back mount analog gauge with a 4.5-inch dial.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Depressurize and isolate the system completely before removing an existing gauge or threading in a new one. Apply thread sealant or PTFE tape to the male threads per the system fluid and local plumbing code requirements. Do not over-tighten the threaded connection, as this can crack the gauge socket; use a wrench on the hex fitting only, not on the case body.
