Value Collection 111CL25100 Pressure Gauge 100 Psi

Product Description

The VALUE COLLECTION 111CL25100 is an analog pressure gauge designed for monitoring system pressure in plumbing, HVAC, and light industrial applications. It features a 2.5-inch dial with a 0 to 100 psi range and a 1/4-inch NPT lower-mount connection. The ABS case houses brass wetted parts and a bronze Bourdon tube, making it suitable for general-purpose liquid and gas pressure measurement where corrosion resistance is needed at the wetted surfaces. Accuracy is rated at plus or minus 3-2-3 percent of scale, which meets the ASME Grade B standard for general service gauges. Licensed tradespeople and experienced service technicians install this type of gauge during system diagnostics, commissioning, and maintenance checks.

This gauge fits lower-mount panel and inline installations where a bottom-entry connection is required. The 1/4-inch NPT thread is the most common connection size in residential and light commercial HVAC, plumbing, and refrigeration service work, making this gauge broadly applicable across those trades. It is a dry gauge with no liquid fill, which keeps it straightforward for applications where vibration dampening is not required. The black dial face provides clear reading against the graduation markings across the full 0 to 100 psi scale.

Key Features

• 2.5-inch analog dial with 0 to 100 psi range for clear, direct pressure reading
• 1/4-inch NPT lower-mount connection fits the most common service port size
• Brass wetted parts and bronze Bourdon tube for corrosion resistance on wetted surfaces
• ABS case construction keeps weight low at 0.2 pounds
• Plus or minus 3-2-3 percent of scale accuracy meets general service gauge requirements
• Dry gauge design with no liquid fill for simple, maintenance-free service

Compatibility

Designed as a general-purpose replacement or service gauge for residential and light commercial systems using 1/4-inch NPT lower-mount connections and operating within a 0 to 100 psi pressure range.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified service professional. Always depressurize the system and relieve all residual pressure before removing an existing gauge or installing a new one. Apply thread sealant tape or pipe compound to the NPT threads before installation and tighten to snug-plus-hand-tight to avoid cracking the case or stripping threads. Verify the gauge pressure range is appropriate for the system before returning the system to service.
