10N50 - Alumina TIG Cup #4 (1/4") for 17/18/26 Torches - 10N50

Reliable #4 TIG Cup for Everyday Welding

Keep your TIG torch running smoothly with this 10N50 Alumina Cup. Known in the shop as a #4 cup, this nozzle is a staple for welders who need to get into tighter corners or who are working on detailed projects where a massive gas envelope isn't necessary. With a 1/4-inch opening, it provides a concentrated stream of shielding gas, helping you lay down clean, porosity-free beads on stainless, chromoly, or mild steel.

If you are running a standard 17, 18, or 26 series torch, this is the cup you need. It fits the standard setup (using a 10N series collet body) and screws on easily. It doesn't matter if your rig is a Miller Syncrowave, a Lincoln Square Wave, or an ESAB machine—if the torch is a 3-series style, this cup fits. It's the perfect backup to keep in your toolbox so you aren't stuck waiting on parts when you drop your torch or crack a cup mid-job.

Made from durable pink alumina ceramic, this nozzle handles the heat. While all ceramic cups will eventually wear out or break if dropped, these are built to resist the thermal shock of starting and stopping arcs all day long. The #4 size is particularly useful when you need to see around the cup or when you are welding in a restricted space where a larger #7 or #8 cup just won't fit.

Don't let overpriced consumables eat into your profit margin. These generic 10N50 cups give you the performance of the big name brands without the premium price tag. Whether you are a hobbyist in the garage or a pro in the fabrication shop, having a fresh stack of #4 cups ensures you are always ready to strike an arc and get the job done right.
