Uniweld UM43F Injector Mixer for Harris Style Handles (Propane/Natural Gas)

Reliable Propane Mixing for Harris Style Torches

If you are running Propane or Natural Gas on your rig, you know that standard mixers just don't cut it. The Uniweld UM43F Mixer Assembly is the solution for welders and fabricators using Harris-style equipment who want to switch to alternative fuels. Designed specifically as an injector mixer, the UM43F solves the problem of low fuel pressure by using the oxygen stream to siphon the gas, giving you a hot, steady flame that won't starve or pop out during use.

This mixer is a direct fit for the popular 43 Series handles (both Uniweld and Harris style), so you don't need to buy a whole new torch setup to change your fuel gas. Just swap out your old mixer for the UM43F, attach your heating or brazing tip, and you are ready to go. It is crafted from solid brass, meaning it can take the knocks of daily shop use and the high heat of prolonged heating cycles without warping or failing.

Whether you are preheating heavy structural steel, brazing copper pipe, or doing general metalworking, the UM43F gives you the control you need. It eliminates the guesswork of setting your flame with alternative fuels and ensures your equipment runs safely. Don't risk flashback or poor performance with the wrong mixer—equip your torch with the Uniweld UM43F and get the most out of your propane supply.
