Campbell pg3t-nl Brass Pressure Gauge 30 Psi Lead-free

Product Description

The CAMPBELL pg3t-nl is a lead-free analog pressure gauge built for low-pressure fluid system monitoring. It features a 2-inch dial and a 1/4-inch NPT lower-mount brass connection, with a maximum pressure rating of 30 psi. The wetted parts are lead-free brass, meeting requirements for potable water applications. A polycarbonate lens protects the dial from impact while keeping readings clear in field conditions. This is a dry, non-liquid-filled gauge, making it best suited for stable systems where significant pulsation or vibration is not present. Plumbers, water treatment technicians, and facilities maintenance personnel commonly install this gauge for routine system pressure indication.

The pg3t-nl is used in residential and light commercial applications including closed-loop plumbing systems, water filtration units, water softeners, and other low-pressure fluid circuits. Its lead-free construction makes it appropriate wherever potable water contact is a compliance requirement. The lower-mount connection allows direct in-line or manifold installation without the need for an additional fitting elbow in most standard configurations.

Installation Notes

Installation is typically performed by a licensed plumber or water treatment technician. Shut off system pressure and depressurize the line completely before removing an existing gauge or threading in this unit. Apply thread sealant tape or pipe thread compound to the NPT threads per local plumbing code requirements before installing. Avoid over-tightening the brass fitting, as this can damage the threaded connection or gauge body.
