Due to the success of the Quick Change Secondary air tube , I have decided to stop making the fully welded tubes.
With the convenience of stub replacement or simply removing your stub for ash cleaning, the welded style is now outdated.
I will still make a welded stub secondary tube (with RA330) by request but all others will be the Quick Change design.
In order to make the Quick Change available to more people worldwide.
I have decided to lower the cost!
The New Lower Price for a Quick Change is now $60 + ship including a carbon steel stub.
Price for a Quick Change secondary with the RA330 stub will be $140 + shipping
