Williams Comfort Products 8G025W Liquid Pressure Gauge

Product Description

The WILLIAMS COMFORT PRODUCTS 8G025W is a liquid-filled pressure gauge with a 2.5-inch face diameter, designed for use in plumbing, hydronic heating, and mechanical systems where accurate pressure monitoring is required. The liquid fill dampens needle movement caused by pressure spikes and vibration, allowing for stable, readable measurements in demanding service conditions. Licensed plumbers and HVAC technicians install this gauge as part of system commissioning, maintenance, and troubleshooting workflows.

This gauge is suited for residential and light commercial applications where a compact, liquid-filled instrument is needed on pressure lines, boilers, pumps, or distribution manifolds. Its 2.5-inch face provides clear readability in tight equipment rooms and mechanical chases. It is sold and installed individually as a direct replacement or new-installation component.

Key Features

• 2.5-inch face diameter for clear, close-range pressure readings
• Liquid-filled construction dampens vibration and pressure-spike needle flutter
• Compact form factor suitable for tight mechanical spaces
• Lightweight at 0.512 pounds for easy single-hand installation

Compatibility

Designed as an OEM-style replacement or new-installation liquid pressure gauge for residential and light commercial plumbing, hydronic heating, and mechanical pressure-monitoring applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Depressurize and isolate the system completely before removing an existing gauge or making any threaded connections. Use appropriate thread sealant or PTFE tape on the gauge port threads and tighten to fitting specifications using an adjustable wrench — do not overtighten, as gauge body damage can result. Verify system pressure is within the gauge rated range before returning the system to service.
