The WEISS INSTRUMENTS tl25-600-4l is a 2.5-inch pressure gauge rated for 0 to 600 PSI service. Gauges in this class are used to monitor system pressure in fluid and gas lines across a wide range of trade applications. The 2.5-inch dial face provides a readable display in tight spaces without sacrificing scale accuracy. Licensed plumbers, HVAC technicians, and mechanical contractors install gauges of this type as part of routine system instrumentation and service work.
This gauge is suited for residential and light commercial applications where a compact, direct-reading pressure instrument is required. Typical installation points include boiler systems, water supply lines, compressed air headers, and hydronic loops. The 0 to 600 PSI range makes it appropriate for higher-pressure service beyond the standard 0-200 PSI range found in basic residential gauges.
Designed as an OEM-style replacement or new-installation pressure gauge for mechanical systems requiring a 2.5-inch, 0 to 600 PSI instrument.
Installation should be performed by a licensed plumber or mechanical contractor in accordance with applicable IPC and IFGC code requirements. Depressurize and isolate the system completely before removing or installing any pressure gauge. Use appropriate thread sealant on the gauge connection and verify the port thread size matches before torquing. Do not exceed the rated 600 PSI maximum operating pressure.
