4000546 - Harris 447 Pipeline Inert Gas Guard Flow Control Regulator

Save Gas and Improve Weld Quality with the Harris Inert Gas Guard

Are you tired of wasting money on shielding gas? The Harris Model 447-80-IGG-1/4 Pipeline Inert Gas Guard Regulator is the solution your shop needs. Designed for use with pipeline systems (station drops), this regulator is specifically engineered to stop the "gas blast" that happens every time you pull the trigger on your MIG gun or TIG torch. That initial surge of gas isn't just noisy; it's money blowing away into the air, and it can actually cause turbulence that sucks oxygen into your weld, causing porosity. By controlling this surge, the Harris IGG ensures you use only the gas you need, delivering significant cost savings over time.

Built by Harris, a leader in gas regulation, this unit is tough enough for any fabrication shop. It features a heavy-duty brass-plated body and bonnet that resists corrosion and wear. The easy-to-turn brass T-screw handle allows you to dial in your flow rate precisely, up to 80 SCFH for Argon or CO2. The large 2-inch gauge is easy to read, so you always know your settings at a glance. Unlike standard regulators that might struggle with the fluctuations of a shop pipeline, the Model 447 uses a rubber diaphragm for smooth, consistent pressure control.

Installation is straightforward with a standard 1/4" NPT inlet for your pipe drop and a 5/8"-18 RH outlet for your gas hose. Inside, a one-piece encapsulated seat with an internal filter keeps dirt and debris from ruining the regulator, ensuring it lasts for years. In fact, Harris is so confident in this product that it comes with a 7-year warranty. Whether you are running a large manufacturing line or a small fabrication booth, the Harris 447-80-IGG-1/4 helps you weld better and spend less on consumables.
