Weldtec/TEC introduced the glass nozzle to TIG torches back in 1955. The original nozzles were made from Pyrex grade glass. These new modern fused quartz nozzles offer superior temperature and thermal shock resistance, surpassing Pyrex, lava, and the pink ceramic nozzles for performance. Now you can use these quartz nozzles on most TIG torches using a simple adapter ring (10NQA for air-cooled & 13NQA-2 for water-cooled). Available in several orifice sizes and several lengths to suit your job requirements. Made in the USA.

These Quartz Nozzles are not compatible with standard gas lens'. They require 45VXXNQ Gas Lens'. Please contact us for pricing and availability.
