OVERVIEW

Get Into Tight Spots with the Weldcraft 12N03 Long Lava Nozzle

Every TIG welder knows the frustration of trying to lay a perfect bead in a spot where the torch just won't fit. Whether you are working on a roll cage, inside a manifold, or in a tight pipe cluster, standard nozzles often block your view or prevent you from getting the tungsten close enough to the joint. The Weldcraft 12N03 Long Lava Nozzle is the problem-solver you need in your kit. With its extended length of over 3 inches, this nozzle acts like a precision extension for your torch, allowing you to reach deep into corners and crevices while maintaining excellent gas coverage.

But reach isn't the only thing this nozzle offers. It is built from "Lava," a tough ceramic material that is far more durable than standard pink alumina cups when things get hot. If you've ever had a standard cup crack or shatter because the heat was bouncing off the metal and back into the torch, you know why Lava is important. These nozzles are built to handle that intense, reflective heat without failing. This means less downtime changing out broken cups and more time welding. It is the kind of reliability professional welders demand when the pressure is on.

This pack contains 10 nozzles, giving you plenty of backups for big jobs. They are sized as a #4 (1/4 inch), which is perfect for fine, detailed work where you need a focused stream of shielding gas. They fit all standard 17, 18, and 26 series torches, so you don't need a special adapter or a different torch body to use them. Just swap out your standard cup, install the 12N03, and you are ready to tackle those impossible-to-reach welds with confidence. Upgrade your consumable arsenal with genuine Weldcraft quality and stop fighting your equipment in tight spaces.

FAQ

The 12N03 fits standard 17, 18, and 26 series TIG torches, as well as compatible models like the 150, 210, 300, and 510 series.

Lava nozzles are made from a ceramic that resists thermal shock and cracking better than Alumina, especially in confined areas where heat is reflected back at the nozzle.

The #4L nozzle has an orifice diameter of 1/4 inch (approximately 6.4mm).

The 12N03 is classified as a "Long" nozzle and measures approximately 3-7/32 inches in length.

A long nozzle allows you to extend the tungsten reach to access tight corners, deep joints, or confined spaces that a standard short cup cannot reach.

This product is sold as a package of 10 nozzles.

While possible, long nozzles are generally used for freehand welding in tight spots. The extra length creates a longer lever arm, making walking the cup more difficult compared to shorter cups.

Yes, this is a genuine Weldcraft product, ensuring high quality and perfect fitment for your torch.
