3H HYDROGEN/OXYGEN HAND TORCH
The National Model 3H Hydrogen Hand Torch is specially designed for use with Hydrogen and Oxygen. The 3H comes with a 7″ stainless steel elbow and has 3/8-24, “A” size, threaded welding hose connections.
Rotating Leak-Proof Union
A specially designed leak-proof “O” ring union permits the tip and elbow assembly to be rotated to any desired angle without the aid of a wrench. Now the flame can be easily directed to allow the most comfortable torch/hand position.
