The National 6B Torch is ideal for dental labs or any bench top application. A nifty feature on the 6B is a 360° free rotating elbow, which has been made possible by including an O-ring on the elbow insuring a positive seal.
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. The elbow can still be set to a fixed position simply by torqueing down the nut.
