Campbell pg1t-nl Brass Pressure Gauge 100 Psi Lead-free

Product Description

The CAMPBELL pg1t-nl is a lead-free, general-purpose mechanical pressure gauge built for reliable analog pressure monitoring across a wide range of service environments. The gauge features a 2-inch dial face with a 1/4-inch NPT lower-mount brass connection, making it a straightforward drop-in solution for systems where lead-free wetted components are required. Brass construction on the wetted parts ensures compatibility with air, water, oil, and other non-corrosive media. Licensed plumbers, HVAC technicians, and service professionals install this type of gauge where code or specification requires lead-free hardware.

The pg1t-nl is suited for residential, commercial, and light industrial pressure monitoring applications. Typical installations include domestic water supply lines, boiler systems, air compressor circuits, irrigation systems, and hydronic heating loops. The lower-mount connection orients the gauge vertically from a threaded port, which is standard on most pump outlets, tank ports, and manifold taps. The analog dial provides a clear, at-a-glance pressure reading without requiring power or instrumentation.

Key Features

• Lead-free construction meets requirements for potable water system installations
• 2-inch dial diameter for clear analog pressure readout
• 1/4-inch NPT lower-mount brass connection for direct port installation
• Compatible with air, water, oil, and other non-corrosive media
• Mechanical gauge design requires no external power source
• Stainless steel case material for corrosion resistance

Compatibility

Designed as an OEM-style replacement or new-installation gauge for residential, commercial, and light industrial pressure monitoring systems using a standard 1/4-inch NPT lower-mount port.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Before installing or removing the gauge, isolate the system and relieve all pressure to zero. Apply thread sealant tape or paste to the male NPT threads before threading the gauge into the port — do not overtighten, as brass fittings can crack under excessive torque. Verify that the gauge range is appropriate for the system operating pressure before returning the system to service.
