ABSTRACT:
A nozzle for delivering cooling gas into the work chamber of a heat treating furnace. The nozzle is formed by a resiliently yieldable metal tube having an overlapping seam and adapted to be contracted radially for insertion through a hole in the wall of the work chamber. After being inserted through the hole, the tube springs outwardly into frictional engagement with the edge of the hole to retain itself in place. Flares on the ends of the tube prevent the tube from shifting endwise relative to the chamber wall.
