Heavy-Duty Harris 3500 Regulator for High Pressure Cylinders

When your welding or industrial application requires high-pressure inert gas supply, the Harris Model 3500-200-680 is the tool for the job. This heavy-duty, single-stage regulator is built to handle the toughest shop environments while delivering precise control. It is specifically outfitted with a CGA 680 inlet fitting, making it compatible with high-pressure inert gas cylinders (Argon, Nitrogen, Helium) rated up to 5500 PSIG. If you are working with specialized high-pressure tanks, this is the regulator you need to step that pressure down safely and effectively.

The Model 3500 is a workhorse in the Harris lineup. It features a time-tested one-piece encapsulated seat design that includes an internal filter. This smart engineering prevents dirt and debris from entering the seating area, which is the number one reason regulators fail in the field. By keeping the seat clean, Harris ensures you get consistent performance and a longer lifespan out of your equipment. The regulator provides a delivery pressure range of 0-200 PSIG, making it versatile for a wide variety of tasks, from purging piping systems to supplying shield gas for large-scale operations.

Constructed with a forged brass body and bonnet, this regulator feels solid in your hand and stands up to the knocks and bumps of daily use. The large, easy-to-read gauges help you monitor cylinder and delivery pressure at a glance.
