Value Collection 116AB20300 Pressure Gauge 300 Psi 2 in

Product Description

The VALUE COLLECTION 116AB20300 is a liquid-filled analog pressure gauge designed for measuring system pressure in HVAC, plumbing, and industrial fluid applications. The glycerine-filled stainless steel case dampens needle vibration and protects internal components in high-cycle or pulsating service conditions. It reads from 0 to 300 psi through a 2-inch analog dial, and connects via a 1/4-inch NPT center back mount thread. Wetted parts and the Bourdon tube are both stainless steel, making this gauge suitable for water, mild chemicals, and other media compatible with stainless construction. Licensed HVAC techs, plumbers, and pipefitters typically install this gauge on pumps, compressors, boilers, and pressurized lines.

This gauge is well suited for residential and light commercial applications where a compact, durable pressure-reading instrument is needed. The center back mount configuration allows flush or panel-mounted installation where a straight-back connection keeps the gauge face perpendicular to the pipe or manifold surface. The 2-inch dial size is readable at close range during service calls and fits standard gauge ports and tee fittings common in hydronic and fluid-handling systems. The glycerine fill reduces wear on the Bourdon tube pointer assembly in environments with steady or intermittent pressure fluctuations.

Key Features

• Pressure range: 0 to 300 psi with analog dial readout
• Accuracy rated at plus or minus 3-2-3 percent of scale across the dial range
• Glycerine liquid fill dampens vibration and prolongs gauge life
• Stainless steel case, Bourdon tube, and wetted parts resist corrosion
• 1/4-inch NPT center back mount for flush or panel installation
• Compact 2-inch dial suited for tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for HVAC, plumbing, and fluid-handling systems requiring a 1/4-inch NPT center back mount connection and a 0 to 300 psi measurement range.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or pipefitter following applicable IPC and IFGC guidelines. Shut down and depressurize the system fully before removing an existing gauge or threading in this unit. Apply appropriate thread sealant or PTFE tape to the NPT threads before installation and hand-tighten before using a wrench to avoid cracking the case or distorting the connection. Do not use this gauge to measure gases or media incompatible with stainless steel wetted parts.
