3000784 - Harris Model 425 Hydrogen Regulator | 0-50 PSIG | CGA 350

Reliable Hydrogen Control with the Harris 425-50A-350

For professional welders and fabricators working with specialized fuel gases, the Harris Model 425-50A-350 offers the perfect blend of rugged durability and precise control. When you are dealing with Hydrogen or Methane, you need equipment that you can trust implicitly. This single-stage regulator is built to withstand the daily abuse of the shop floor while delivering the consistent performance required for high-quality work. Whether you are setting up a specialized heating application or a laboratory supply line, the Model 425 is the workhorse you need.

Built for the Shop Environment

We know that tools in a welding shop take a beating. That is why the Harris 425 features a heavy-duty brass body and bonnet. It feels solid in your hand and stands up to accidental knocks and bumps. The adjusting knob is a brass "T" screw handle, designed to be easy to operate even when you are wearing heavy welding gloves. You won't have to fumble with small plastic knobs; just a smooth, positive turn gives you the exact pressure you need. The large 2.5-inch gauges are easy to read from a distance, so you can check your tank levels and line pressure at a glance without stopping your work.

Performance You Can Feel

Inconsistent gas flow can ruin a project. The Harris 425 utilizes a neoprene diaphragm which provides excellent sensitivity. This means when you set your pressure to 20 PSIG, it stays there. You get a smooth, steady flow of gas without the "creep" that plagues cheaper regulators. The internal design features a special encapsulated seat with a built-in filter. This is a huge advantage because it stops dirt and grit from the tank from getting into the regulator's sensitive parts. This translates to fewer repairs, less downtime, and a regulator that lasts for years.

Peace of Mind

Safety is non-negotiable. This regulator comes with a built-in safety relief valve that automatically reseats itself, protecting your equipment and your shop. Plus, it is made in the USA and comes with a massive 7-year warranty. That is seven years of guaranteed performance from one of the most trusted names in the industry. If you need a CGA 350 regulator that just works, day in and day out, the Harris 425-50A-350 is the smart choice for your toolkit.
