Value Collection 115AB20100 Pressure Gauge 100 Psi 2 in

Product Description

The VALUE COLLECTION 115AB20100 is a liquid-filled analog pressure gauge designed for monitoring system pressure in plumbing, HVAC, and general industrial piping applications. The gauge features a 2-inch diameter dial with a 0 to 100 psi range and a glycerine-filled case that dampens needle vibration for stable readings in pulsating or vibrating systems. The stainless steel case resists corrosion, while the brass wetted parts and bronze Bourdon tube provide reliable performance in water, glycerine, and compatible fluid systems. Accuracy is rated at 3-2-3 percent of scale across the full range. Installation is handled via a 1/4-inch NPT center back mount connection.

This gauge is suited for residential and light commercial service where a compact, liquid-filled instrument is needed on hydronic heating systems, potable water lines, compressed air circuits, or boiler supply and return piping. The center back mount configuration positions the connection straight through the back of the case, making it a good fit for panel-mount or pipe-stub installations where a direct rear-entry connection is preferred. Licensed plumbers and HVAC technicians are the typical installing trades.

Key Features

• Glycerine-filled case dampens vibration and reduces needle flutter for steady pressure readings
• 0 to 100 psi range with 3-2-3 percent of scale accuracy
• Stainless steel case for corrosion resistance in wet or outdoor-adjacent environments
• Brass wetted parts and bronze Bourdon tube compatible with water and glycerine service
• 1/4-inch NPT center back mount for straightforward panel or pipe-stub installation
• Compact 2-inch dial suitable for tight equipment rooms and control panels

Compatibility

Designed as a general-purpose replacement or new-installation analog pressure gauge for residential and light commercial plumbing, HVAC hydronic, and compressed air systems requiring a 1/4-inch NPT center back mount connection with a 0 to 100 psi range.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and depressurize the system fully before removing an existing gauge or threading in a new one. Apply thread sealant tape or compound to the NPT threads before installation — do not overtighten, as brass fittings can crack under excess torque. Verify that the gauge range and wetted materials are compatible with the fluid and pressure conditions of the target system before placing in service.
