Where Does This Adapter Fit?
The image below shows the correct orientation and position in the connection of a borosillicate glass mouthpiece to the NOVA Hookah hose.
Cleaning
Cipher recommends soaking in hot soapy water or 91% Isopropyl Alcohol periodically to keep the mouthpiece adapter clean and free of sticky resin buildup. Especially when smoking in colder environments, resin does tend to buildup faster, which may be noticed by more restricted air flow when inhaling from the NOVA Hookah mouthpiece. A quick fix for restricted air flow is to remove the glass mouthpiece from the adapter and run the adapter under hot water for a few seconds. Then, blow through one end to expel the resin.
O-Ring Replacement
Depending on how often the glass mouthpiece is removed, the o-rings will eventually need to be replaced. The indication that it's time to replace the o-rings is when you find it difficult to insert the glass mouthpiece onto the adapter. To remove the o-rings, use a sharp knife to slice the o-ring as shown in the picture below. Alternatively, you can use a very small flat tip object or tweezers to pry underneath the o-ring.
