Value Collection 111CB20V30 Pressure Gauge 2 in 30 Psi Npt

Product Description

The VALUE COLLECTION 111CB20V30 is an analog pressure gauge designed for low-pressure measurement in plumbing, HVAC, and general industrial service applications. It features a 2-inch diameter dial with a compound pressure range of -30 to 0 to 30 psi, making it suitable for both vacuum and positive pressure readings. The case is constructed from ABS plastic and the wetted parts are brass, with a bronze Bourdon tube providing the sensing element. Accuracy is rated at plus or minus 3-2-3 percent of scale across the full range. This gauge is a dry (non-liquid-filled) unit and mounts via a 1/4-inch NPT center back connection.

This gauge is well suited for residential and light commercial installations where low-pressure monitoring is required. Common applications include refrigeration service, hydronic heating systems, compressed air lines, and water supply systems operating within the -30 to 30 psi range. The center back mount configuration fits standard panel and pipe installations. Licensed plumbers, HVAC technicians, and pipefitters typically source this gauge for diagnostic setups and permanent system monitoring points.

Key Features

• Compound range from -30 to 30 psi covers both vacuum and positive pressure in a single gauge
• 2-inch analog dial with black face for clear at-a-glance reading
• Brass wetted parts and bronze Bourdon tube resist corrosion in water and air service
• ABS case construction keeps weight low at 0.15 pounds
• 1/4-inch NPT center back mount for straightforward panel or inline installation
• Dry gauge design with plus or minus 3-2-3 percent of scale accuracy

Compatibility

Designed as a direct-fit analog pressure gauge for systems requiring a 1/4-inch NPT center back mount connection and a compound pressure range up to 30 psi.

Installation Notes

Install by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable local codes and ASME B40.100 guidelines for pressure gauges. Shut off and depressurize the system fully before removing or installing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads before hand-tightening and finishing with a wrench, taking care not to overtighten and crack the ABS case. Do not use this gauge on systems with fluids or pressures outside the rated range.
