Value Collection 116AL25030 Pressure Gauge 30 Psi Npt

Product Description

The VALUE COLLECTION 116AL25030 is an analog pressure gauge designed for monitoring system pressure in plumbing, HVAC, and industrial fluid systems. It features a 2.5-inch dial face and reads from 0 to 30 psi with a 3-2-3 percent of scale accuracy rating. The case and all wetted parts are stainless steel, making it suitable for mildly corrosive environments. The gauge is liquid-filled with glycerine or water to dampen needle vibration and extend service life. It mounts via a 1/4-inch NPT lower connection and is installed by plumbers, HVAC technicians, and pipefitters on pumps, compressors, water systems, and pressure vessels.

This gauge fits residential and light commercial applications where a compact, low-range pressure gauge is needed. Common installations include domestic water systems, boiler supply lines, air compressor outlets, filtration systems, and hydronic heating loops. The lower-mount configuration positions the connection at the base of the gauge, allowing flush or panel-mount installations where a back or side connection is not practical. The 2.5-inch dial provides clear readability in close-quarters mechanical rooms or equipment cabinets.

Key Features

• 0 to 30 psi range with 3-2-3 percent of scale accuracy for reliable low-pressure monitoring
• Stainless steel case and wetted parts for corrosion resistance in wet or mildly aggressive service
• Glycerine or water liquid fill dampens vibration and pulsation for stable needle reading
• 2.5-inch analog dial face for clear, at-a-glance pressure readings
• 1/4-inch NPT lower-mount connection for standard threaded pipe fittings

Compatibility

Designed as a standard replacement or new-installation pressure gauge for any system using 1/4-inch NPT lower-mount fittings with a service pressure within the 0 to 30 psi range.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician in accordance with applicable IPC or IFGC guidelines. Shut down system pressure and relieve all residual pressure before removing or installing any gauge. Apply thread sealant tape or pipe compound to the NPT threads before tightening — do not overtighten, as this can crack the gauge socket. Verify that the gauge pressure range is appropriate for the system before returning it to service.
