Reliable Inert Gas Control with Harris 301 Series

When you are out in the field performing HVAC pressure tests or purging lines with Nitrogen, you need a regulator that is both lightweight and tough enough to handle the job. The Harris 301-100-580 Inert Gas Regulator is built exactly for these scenarios. Made in the USA, this compact regulator doesn't cut corners on quality. It features a rugged brass body that resists corrosion and wear, ensuring it stays in your toolkit for years to come. In fact, Harris is so confident in its construction that they back it with a 7-year warranty.

Precision is critical when testing systems for leaks or maintaining purge pressure. The Harris 301 delivers accurate pressure regulation up to 100 PSIG, easily adjustable with a smooth brass "T" handle. The dual 2-inch steel gauges are easy to read, letting you monitor your tank level and output pressure at a glance.

One of the biggest frustrations with regulators is seat failure due to dirt or debris. Harris solves this with a smart, one-piece encapsulated seat design that includes an internal filter. This protects the critical Teflon seat from contaminants, significantly extending the life of the regulator and reducing maintenance headaches. For welders and technicians looking for a dependable, no-nonsense regulator for inert gases, the Harris 301 is a proven choice.
