3000762 - Harris Model 425 Heavy-Duty Industrial Air Regulator (CGA 346)

Harris Model 425-125-346 Single Stage Industrial Air Regulator

The Harris Model 425-125-346 is a premium, heavy-duty single-stage regulator designed specifically for industrial air applications. Engineered by the Harris Products Group, a leader in gas regulation technology, this model is built to withstand the rigors of daily industrial use while providing precise and reliable pressure control. The regulator features a CGA 346 inlet connection, the standard for industrial air cylinders, ensuring compatibility and safety in your facility.

At the core of the Model 425 is its robust construction. The body and bonnet are machined from solid brass, offering superior resistance to corrosion and physical damage compared to lighter-duty alternatives. This durability is backed by Harris's industry-leading 7-year warranty, giving you peace of mind and long-term value. The regulator is designed with a neoprene diaphragm, which provides excellent flexibility and sensitivity, allowing for accurate pressure adjustments even at lower flow rates. This makes it an ideal choice for pneumatic tools, testing equipment, and general shop air supply.

One of the standout features of this regulator is the one-piece encapsulated seat design. This innovative component includes an internal filter that protects the PTFE Teflon® seat from particulate contamination—a common cause of regulator failure. By filtering out debris before it reaches the critical sealing surface, the Model 425 ensures a longer operational life and reduced maintenance downtime. The regulator also features large, easy-to-read 2.5-inch brass gauges that display both cylinder pressure and delivery pressure, allowing operators to monitor system status at a glance.

Safety is paramount in the design of the Harris 425-125-346. It is equipped with a tamper-proof, self-reseating internal safety relief valve that protects components and personnel in the event of an over-pressure situation. The ergonomic brass "T" screw handle makes adjusting delivery pressure smooth and effortless, up to a maximum of 125 PSIG. Whether you are outfitting a new workshop or replacing aging equipment, this US-made regulator delivers the performance and reliability professionals demand.
