Value Collection 116AL35100 Pressure Gauge 100 Psi Npt

Product Description

The VALUE COLLECTION 116AL35100 is a liquid-filled analog pressure gauge designed for accurate pressure monitoring in plumbing, HVAC, and industrial fluid systems. The gauge features a 4-inch dial with a 0 to 100 psi range and an accuracy rating of 1 percent of full scale, making it suitable for applications where reliable readings are required. A glycerine and water fill dampens pointer vibration and protects internal components from pressure spikes. The stainless steel case and stainless steel wetted parts provide corrosion resistance in wet or chemically active environments. The 1/4-inch NPT lower-mount connection suits panel and inline installations. Licensed plumbers, HVAC technicians, and industrial maintenance professionals are the typical installers.

This gauge is suited for residential and commercial applications where fluid or gas pressure must be monitored continuously. The lower-mount NPT connection is a common configuration for boilers, water supply lines, compressed air systems, hydronic heating loops, and process piping. The liquid fill makes this gauge a practical choice for systems with pulsating flow or vibrating equipment, such as pumps and compressors. The 4-inch dial provides legible readings at a distance on mechanical rooms or equipment skids.

Key Features

• 0 to 100 psi range with 1 percent of full-scale accuracy
• Liquid filled with glycerine and water for vibration and pulsation dampening
• 4-inch analog dial for clear, at-a-glance reading
• Stainless steel case and wetted parts for corrosion resistance
• 1/4-inch NPT lower-mount connection for standard inline or panel installation

Compatibility

Designed as a standard replacement or new-installation pressure gauge for systems using 1/4-inch NPT lower-mount fittings, including plumbing, HVAC, and fluid process applications rated up to 100 psi.

Installation Notes

Installation should be performed by a licensed plumber or qualified technician following applicable local codes and manufacturer guidelines. Shut off and depressurize the system completely before removing any existing gauge or installing this unit. Use an appropriate thread sealant on the NPT threads and avoid over-tightening, which can damage the gauge body or fitting. Verify system pressure range is within the 0 to 100 psi rating before returning the system to service.
