Important note for customers with used or existing parts:


"Metalbestos" is a brand name. It is hard to tell from a picture and there are many similar looking products out there. Three from the same manufacturer as Metalbestos (Selkirk) that look the same but do not lock together. The older style Metalbestos pipe was model "SS" or "SS-II" where as the newer product is designated "UT" and have had returns from customers that say they don't work together either. This could be user error.

However after contacting Selkirk about all the confusion we have added this response from the manufacturers tech department:

No adapter is needed since we never changed the coupling design. The testing through Underwriters Laboratories, Inc. changed to include an optional high temperature test. At that time the model designation was changed, but not the product. A few years ago we once again changed the model designation (to the Model UT you reference) but not the basics of the product. There is still the twist lock coupler with the separate locking band, the required 2" air space clearance, etc. so you'll not have any problems getting the pieces to connect.

We apologize for any incorrect information we have given out in the past about these not working but without the consent from Selkirk we did not want the liability of mixing and matching products of this nature and the bad reputation that comes with shipping improper parts to people and wasting their time and money.
