Koike Style 106-3 Propane Cutting Nozzle

Get Clean Cuts with the 106-3 Propane Tip

If you are running a Koike-style torch and prefer the economy and availability of propane over acetylene, the GEN106-3 cutting tip is an essential consumable for your kit. This Size #3 nozzle is the workhorse for medium-plate cutting, easily slicing through steel up to an inch and a half thick. The secret to its performance lies in its 2-piece design. Propane burns differently than acetylene; it requires a specific tip architecture to keep the flame stable. This tip features a splined brass insert inside a heavy-duty copper shell, creating a robust preheat flame that won't starve or blow out when you trigger the cutting oxygen.

Welders and fabricators know that spatter buildup is the enemy of a good cut. That's why this tip comes with a high-quality chrome finish. The chrome acts as a shield, preventing hot slag from sticking to the nozzle. This means you spend less time scraping your tip and more time cutting metal. When you do need to clean it, the spatter usually wipes right off. The precision bore ensures your cutting stream is tight and focused, giving you a clean edge that often needs little to no grinding before welding.

Switching to this generic 106-3 tip is a smart move for budget-conscious shops. You get the reliability of a standard Koike tip without the premium price tag. It installs easily into any torch setup for 106 series tips—just hand tighten the nut and give it a slight wrench snug (don't over-torque!). Whether you are cutting scrap, shaping brackets, or trimming beams, this tip provides the heat and control you need to get the job done right. Remember to check your regulator settings; propane tips generally run at different pressures than acetylene, and dialing it in correctly will give you that smooth, hissing preheat sound that tells you you're ready to cut.

Don't let worn-out nozzles ruin your work. A fresh tip like the GEN106-3 restores your torch's ability to pierce and sever steel cleanly, reducing gas waste and frustration. Keep a few in your box so you're always ready for the next heavy plate job.
