The National Model 3C Hand Torch is specifically designed for use with acetylene and oxygen. The 3C comes with a brass 4-1/2″ 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.
