Strangely; with the troubles I have had trying to locate these small
o-rings that can take Acetylene, I contacted Smith again. And they
said that there are no o-rings at that location.
I did buy my torch used, it is actually an older Tescom model, which
is the old name of Smith. It has the same model number as the
So, either they had 0-rings back then, or it was modified.
I did check the local hardware store, and they did not have one
small enough either (it wasn’t a Home Depot)
I guess I will try to connect it without the rings to see if it
leaks. If it does, I have a little challenge on my hands.
