Don't let a broken or unreadable gauge compromise your welding projects. The Victor 21866 Replacement Gauge is the professional's choice for fixing damaged gas regulators. Designed with a 0-100 PSI range, this gauge is primarily used to monitor delivery pressure—the pressure leaving the regulator and going to your torch or machine. Accurate delivery pressure is vital for maintaining a stable arc in MIG/TIG welding and for achieving clean cuts in oxy-fuel applications.
This gauge features a standard 2-inch diameter case, which is the perfect size to fit neatly on most regulator bodies without obstructing the handle or other controls. The white face contrasts sharply with the black needle and numerals, making it incredibly easy to read from a distance. This visibility is crucial when you are under the hood or adjusting settings on the fly. The connection is a universal 1/8-inch NPT male thread, usually located at the bottom of the gauge (bottom mount), which screws directly into the regulator's low-pressure port.
While generic gauges exist, the Victor 21866 is built to withstand the rigors of the welding environment. Cheap substitutes often suffer from "needle bounce" or lose calibration quickly. Victor gauges are constructed with quality brass internals that resist corrosion and provide smooth, steady needle movement. This ensures that when you set your regulator to 15 PSI, you are actually getting 15 PSI.
Installing the Victor 21866 is straightforward. Simply ensure the system is fully depressurized, remove the old gauge with a wrench (applying force to the brass stem, not the case), apply a small amount of PTFE tape or thread sealant to the new gauge threads (being careful not to block the inlet), and tighten it into place. Always leak-check your connection with a soapy water solution before use. This simple repair can extend the life of your expensive regulator and ensure your welds remain consistent.
