Trerice 760b Pressure Gauge 0-20 Oz/sq in 2.5 in Dial

Product Description

The TRERICE 760b is a low-range dial pressure gauge designed to measure pressure in ounces per square inch and inches of water column. It features a 2.5-inch dial face with a measurement range of 0 to 20 oz/sq in, equivalent to 0 to 34 inches H2O. The 1/4-inch NPT lower-mount connection makes it straightforward to install inline or on a tapped port. This type of gauge is commonly specified by HVAC technicians, plumbers, and balancing contractors who need accurate low-pressure readings in duct systems, hydronic piping, or air handler applications.

Low-range pressure gauges like the 760b are used where standard PSI-range gauges lack the resolution needed for accurate readings. Typical applications include measuring static pressure in ductwork, monitoring low-pressure gas lines, checking draft conditions, and verifying pressure drop across filters or coils in commercial and residential HVAC systems. The lower-mount NPT connection is suited for panel mounting or direct pipe-port installation.

Key Features

• Dual-scale dial reading: 0-20 oz/sq in and 0-34 inches H2O
• 2.5-inch dial face for easy field reading
• 1/4-inch NPT lower-mount process connection
• Low-pressure range suited for duct, hydronic, and draft applications
• Compact form factor for tight installation locations

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for low-pressure measurement points in residential and commercial HVAC, plumbing, and mechanical systems requiring 1/4-inch NPT lower-mount connections.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber. Shut off system pressure and relieve any residual pressure in the line before removing or installing the gauge. Use appropriate thread sealant on the NPT threads and tighten to hand-tight plus wrench-snug — do not overtighten, as this can crack the gauge body. Verify the system operating pressure does not exceed the gauge maximum range before returning the system to service.
