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

Industrial Grade Weldcraft 13N17 Lava TIG Nozzle

The Weldcraft 13N17 Lava Nozzle is a specialized TIG welding consumable designed to address the challenges of high-heat environments and confined space welding. Unlike standard alumina oxide cups, this nozzle is manufactured from a unique lava material—a fired ceramic derived from talc or soapstone—which possesses exceptional thermal properties. This material composition allows the nozzle to withstand severe thermal shock and high temperatures without cracking, a common failure point in standard ceramic cups when used in tight corners or deep grooves where heat is reflected back onto the torch front end.

This specific nozzle features a #7 orifice size, measuring 7/16 of an inch, which provides a balanced shielding gas coverage suitable for a wide range of joint configurations and material thicknesses. It is engineered to fit all standard 9 Series (air-cooled) and 20 Series (water-cooled) TIG torch bodies, ensuring broad compatibility across equipment fleets. The precision threading ensures a secure fit to the collet body or gas lens, preventing gas leakage and ensuring laminar flow for high-quality weld deposits.

At Josef Gas, we understand that equipment reliability directly impacts production timelines. The 13N17 is favored by pipe welders, aerospace fabricators, and maintenance professionals who frequently encounter restricted access welds. By utilizing a lava nozzle in these applications, operators can significantly reduce the frequency of consumable replacement, thereby lowering long-term operational costs. This product is supplied in a pack of 10, ensuring your tool crib remains stocked for continuous operation.

Whether you are welding stainless steel manifolds or aluminum heat exchangers, the Weldcraft 13N17 offers the durability required for precision TIG applications. Its robust construction resists the abuse of industrial environments, making it a superior choice for applications where standard nozzles fail prematurely due to heat stress.
