Trerice 842615106575 Pressure Gauge 100 Psi 4.5 in Brass

Product Description

The TRERICE 842615106575 is a lower-mount pressure gauge from the 600CB Series, designed for commercial and construction plumbing applications. It features a 4.5-inch diameter dial with a 0 to 100 psi range, housed in a cast aluminum case with a black finish. The wetted components use lead-free brass that meets NSF/ANSI 372 and NSF/ANSI 61 standards, making it suitable for potable water systems. UL Listed and built to ASME B40.100, this gauge delivers reliable pressure indication at a practical price point for licensed plumbing and mechanical contractors.

This gauge is used in commercial plumbing and HVAC piping systems where accurate pressure monitoring is required at moderate temperatures. The 0.25-inch male pipe thread (MPT) lower-mount connection fits standard pipe installations in boiler rooms, mechanical rooms, pump stations, and similar service environments. It is rated for fluid temperatures up to 212 degrees F, covering most hot-water and steam-adjacent applications in residential and light commercial service.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor in accordance with applicable local codes and IPC guidelines. Shut off system pressure and depressurize the line completely before removing or installing any gauge. Apply thread sealant tape to the MPT threads and hand-tighten before using a wrench to avoid overtightening the brass fitting. Verify the system operating pressure does not exceed the 100 psi maximum rated range of this gauge.
