Q: The OD of the Airstream mouthpiece threads is smaller (about 1/8”) than the ID of my blow stick threads. Can anything be added to help join the two or do I have to purchase the whole blow stick assembly? I’m trying to keep my stick blow stick if possible and just change out the mouthpiece. McCallum AB4 pipes.
A: If the blowpipe threads are smaller then the mouthpiece threads, then you can use plumbers tape or Teflon tape to build up the threads to accept the slightly larger mouthpiece threads.
Q: Would the Airstream Mouthpiece fit the McCallum blowpipe extension I just purchased. I have another new mouthpiece , but the threads don't match.
A: Hello, Yes, these items are compatible.
