Shank

A brazing heating torch shank is the part of the torch that connects the torch body to the oxygen and fuel gas hoses. It is available in two main types: lightweight and heavy duty.

• Lightweight brazing torch shanks are made of aluminum or brass and are designed for use with smaller torches and lighter applications. They are typically less expensive than heavy duty shanks and offer better overall dexterity. However, they are not as versatile and do not have the same range of available accessories as heavy duty shanks.
• Heavy duty brazing torch shanks are made of steel and are designed for use with larger torches and heavier applications. They are more expensive than lightweight shanks but offer greater versatility and a wider range of available accessories. They are also physically heavier than lightweight shanks.

The type of brazing torch shank that you choose will depend on the specific application that you will be using it for. If you are only going to be using the torch for small, lightweight jobs, then a lightweight shank will be sufficient. However, if you need a more versatile torch that can handle heavier applications, then a heavy duty shank is the better choice.
