Good morning to all! I want to apologize for my English. I'm from Spain (Barcelona) and I'm using the google translator because my English is very bad, Sorry!! I've asked several of my community forums with no answer, so I turn to you, because the level there here is far superior to the rest. I'm looking for an adapter for bubbler to: -14.4 Mm 18mm female to female -14.4 Mm 14mm female to female -18.8 Mm 14mm female to female -18.8 Mm 18mm female to female Only to find one of these features and serve me. I searched all over the net and have not known where to find it or how I could fix. To see if you think of something you. Thank you very much for everything and good smoke!
