3000767 - Harris Model 425 Heavy Duty Regulator, CGA-580, 0-125 PSIG

Harris Model 425 Heavy Duty Single-Stage Regulator

The Harris Model 425-125-580 is a premium, heavy-duty single-stage regulator designed to meet the rigorous demands of industrial gas control. Engineered for versatility and durability, this regulator is specifically configured for use with inert gases such as Argon, Helium, and Nitrogen, utilizing a standard CGA-580 inlet connection. It provides a reliable delivery pressure range of 0 to 125 PSIG, making it an ideal choice for a wide spectrum of manufacturing, fabrication, and maintenance applications where consistent pressure regulation is critical.

At the core of the Model 425's reliability is Harris's signature one-piece encapsulated seat design. This advanced engineering feature incorporates an internal filter that actively protects the PTFE Teflon seat from particulate contamination, a common cause of regulator failure. By preventing debris from entering the high-pressure seating area, the regulator maintains a positive seal and significantly extends its operational lifespan. Furthermore, the unit utilizes a robust neoprene diaphragm which offers superior flexibility and sensitivity compared to stainless steel diaphragms in this class, allowing for precise pressure control and rapid response to flow changes.

Constructed with a forged brass body and bonnet, the Model 425 is built to withstand the physical abuse typical of industrial environments. The regulator is equipped with large, 2.5-inch brass dual-scale gauges that provide clear and accurate readings of both cylinder and delivery pressure. Safety is paramount in the design, featuring a tamper-proof, self-reseating internal high-pressure safety valve that protects the downstream equipment and personnel. Manufactured in the USA and backed by an impressive 7-year warranty, the Harris Model 425 stands as a testament to quality craftsmanship and engineering excellence in gas control equipment.
