819-0 - Air Liquide Style 819-0 Propane Cutting Nozzle

Reliable Cuts with the 819-0 Propane Tip

If you are running an Air Liquide torch and burning Propane or Natural Gas, the 819-0 Cutting Tip is the reliable workhorse you need for your daily cutting tasks. We know that in the field, you need consumables that just work—parts that seat correctly the first time, light up easily, and hold a steady flame even when you're working outdoors or in drafty shops. This generic replacement tip gives you OEM-level performance without the premium price tag, helping you keep your operating costs down without sacrificing cut quality.

This is a Size 0 tip, which is perfect for that sweet spot of material thickness you encounter every day—roughly 1/4" to 1/2" steel plate. It’s not too big, so you aren't wasting oxygen on thin sheets, but it has enough punch to handle bracketry, light structural frames, and general repair work. Because it is designed for Propane, it features a two-piece design. You have a solid brass outer shell that protects the internals and a copper inner piece with splines. Those splines are crucial; they help keep your preheat flame attached to the tip so it doesn't blow out when you hit the cutting oxygen lever.

Why Choose This Tip?

Propane cutting is great because the gas is cheaper and the cuts are often cleaner with less slag on the bottom edge compared to acetylene, provided you use the right tip. The 819-0 is built to maximize those benefits. The heavy recessed tip end protects the preheat holes from damage if you accidentally bump the plate, and the two-piece design makes cleaning a breeze. If the tip gets clogged with splatter, you can slide the inner part out and clean the splines gently with a wire brush—much easier than trying to ream out a solid one-piece acetylene tip.

Pro Tip: Since this is a propane tip, remember that your preheat time might be slightly longer than with acetylene, but once you get the puddle, this tip will slice through steel smoothly. Make sure to set your oxygen and fuel pressures according to the chart for a Size 0 tip to prevent backfires and ensure the cleanest cut face. Whether you are scrapping, fabricating, or doing farm repairs, this 819-0 tip is a solid addition to your torch kit.
