Value Collection 116AB20030 Pressure Gauge 30 Psi 2 in Npt

Product Description

The VALUE COLLECTION 116AB20030 is a liquid-filled analog pressure gauge designed for accurate, low-range pressure monitoring in plumbing, HVAC, and industrial process applications. The gauge reads from 0 to 30 psi with a 3-2-3 percent of scale accuracy rating, making it suitable for low-pressure system diagnostics and system commissioning work. A glycerine-filled case dampens needle vibration and protects the Bourdon tube against pressure spikes. The 2-inch dial provides a clear, readable display in tight installation environments. All wetted parts and the case are constructed from stainless steel, providing corrosion resistance in wet or chemically active service conditions. Licensed plumbers, HVAC technicians, and pipefitters are the typical installers.

This gauge is suited for residential and light commercial applications where low-pressure monitoring is required, including water supply lines, boiler systems, compressed air circuits, and hydronic heating loops. The 1/4-inch NPT lower mount connection allows direct inline installation on standard threaded fittings commonly found in these systems. The glycerine fill makes it appropriate for moderate-vibration environments where a dry gauge would lose accuracy over time. Stainless steel wetted parts allow use with water, mildly corrosive fluids, and glycerine-water mixtures.

Key Features

• 0 to 30 psi range with 3-2-3 percent of scale accuracy for low-pressure system work
• Glycerine liquid fill dampens vibration and protects internal components from pressure spikes
• Stainless steel case and wetted parts for corrosion resistance in wet service
• 2-inch analog dial for clear readings in confined spaces
• 1/4-inch NPT lower mount connection for standard inline installation

Compatibility

Designed as a direct-install replacement or new-installation gauge for any system with a 1/4-inch NPT lower-mount port requiring 0 to 30 psi range monitoring.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians in accordance with applicable IPC or IFGC requirements. Depressurize and isolate the system before installing or replacing the gauge. Apply thread sealant or PTFE tape to the NPT threads before threading the gauge into the port — do not overtighten, as stainless steel fittings can gall. Verify the pressure range of the system does not exceed 30 psi at any operating condition before placing this gauge in service.
