13N17 - Weldcraft 13N17 Lava Cup #7 for 9/20 Torches (10-Pack)

Weldcraft 13N17 Lava Nozzle #7 (10-Pack)

Upgrade your TIG torch setup with the genuine Weldcraft 13N17 Lava Nozzle, specifically designed for welders who demand durability and performance in challenging conditions. This #7 size cup (7/16-inch bore) is a critical accessory for anyone operating a 9 Series or 20 Series TIG torch. While standard pink alumina cups are sufficient for general bench work, they often crack or shatter when subjected to the intense reflected heat found in tight corners, pipe roots, or restricted access joints. This is where the 13N17 Lava nozzle excels.

Manufactured from a specialized lava material, this nozzle offers superior resistance to thermal shock. It can handle rapid temperature changes and prolonged exposure to reflected arc heat that would destroy lesser consumables. This makes it the go-to choice for pipe welders, motorsports fabricators, and repair technicians working inside engine bays or complex assemblies. The #7 size offers excellent versatility, providing a gas coverage area that is wide enough for most fillet and butt welds while remaining compact enough to maintain visibility of the tungsten and the weld pool.

Welders Supply provides these nozzles in a convenient package of 10, ensuring you have plenty of spares on hand for big jobs. Using genuine Weldcraft parts guarantees that the threads will mate perfectly with your torch's collet body, eliminating the frustration of cross-threading or loose fits that can lead to air aspiration and porosity in your welds. The lava material also stands up to more physical abuse than standard ceramics, meaning fewer trips to the supply cabinet and more time under the hood.

Don't let cracked cups slow down your workflow. Switch to the Weldcraft 13N17 Lava Nozzle for your 9/20 torch setup and experience the difference in longevity and reliability. Whether you are running high amperage on a water-cooled 20 torch or precision welding with an air-cooled 9 torch, this nozzle delivers the consistency professional welders rely on.
