Value Collection 115AL25030 Pressure Gauge 30 Psi Lower Mount

Product Description

The VALUE COLLECTION 115AL25030 is a liquid-filled analog pressure gauge designed for monitoring system pressure in plumbing, HVAC, and light industrial applications. The gauge features a 2.5-inch dial with a 0 to 30 psi range, a lower-mount 1/4-inch NPT connection, and a glycerine-filled case that dampens needle vibration for steady readings in high-cycle or pulsating-flow systems. The stainless steel case resists corrosion in wet or outdoor service environments. Accuracy is rated at plus or minus 3-2-3 percent of scale. A licensed plumber, HVAC technician, or pipefitter typically handles installation of gauges of this type.

This gauge is suited for residential and light commercial systems where a compact 2.5-inch face and lower-mount NPT fitting are required. Common applications include water pressure monitoring on supply lines, boiler systems, compressed-air headers, and hydronic loops operating at or below 30 psi. The bronze Bourdon tube and brass wetted parts are compatible with water, glycerine solutions, and other non-corrosive media. The glycerine fill helps maintain readability in environments with vibration or pressure fluctuation.

Key Features

• 0 to 30 psi analog pressure range with plus or minus 3-2-3 percent of scale accuracy
• 2.5-inch dial diameter for clear, at-a-glance readings
• Glycerine liquid fill dampens vibration and pulsation for stable needle position
• Lower-mount 1/4-inch NPT connection for direct inline or manifold installation
• Stainless steel case provides corrosion resistance in wet service environments
• Brass wetted parts and bronze Bourdon tube suited for water and non-corrosive media

Compatibility

Designed as a standard replacement or new-installation pressure gauge for plumbing, HVAC, and light industrial systems using 1/4-inch NPT lower-mount fittings with a maximum operating pressure of 30 psi.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Shut off system pressure and depressurize the line fully before threading the gauge into the fitting. Apply thread sealant or PTFE tape to the NPT threads per IPC and local code requirements. Do not over-tighten the gauge body; use the hex flats on the connection fitting to avoid stressing the case or Bourdon tube.
