When setting up a Hookah air system, you will frequently need an array of metal fittings. For use around water, you should use stainless steel or brass fittings only.

A hookah (Farsi: ÙÙÛØ§Ù Urdu: Ø­ÙÙÛ (Nastaleeq), IPA: [ËÉ¦ÊqqaË]; also see other names) is a single- or multi-stemmed instrument for vaporizing and smoking flavored tobacco (called Muâassel), or sometimes cannabis, whose vapor or smoke is passed through a water basinâoften glass-basedâbefore inhalation.
