Hookah breathing air hose is made of a special vinyl plastic construction, which is resistant to the effects of oil, gasoline and sunlight that exists in the environment. Conventional rubber scuba hose should never be used for hookah diving because it will gradually deteriorate and become toxic. Hookah hose commonly has an inside diameter of 8 mm or 10 mm. It is constructed of an inner liner of food-grade vinyl wrapped with a nylon webbing reinforcement and covered with a heavy-duty PVC abrasion resistant wall. Hookah hose is designed to prevent kinking and collapsing which could cause the flow of breathing air to be shut off.
A quality surface supply diving systems hose will be coloured a bright yellow or orange, for a high degree of visibility. It will also float, so that any excess hose not actually being used will float on the surface, completely away from the diver, reducing the possibility of entanglements on the bottom. For example, if you are diving in three metres of water but are using a 10-metre length of air hose, the excess seven metres will float on the surface, completely away from you. A quality Hookah air will not impart any flavouring to the air and should meet AS2299 and AS1716 standards.
We recommend the use of high-quality, Australian made Barfell® Divers Air Breather Hookah hoses with an inside diameter of 8 mm for recreational diving and 10 mm for commercial diving. The Barfell hookah hoses meet Australian Standards AS2299 and AS/NZ1716.
We also recommend the use of commercial-grade lockable Unoflow® quick couplings for safe hookah diving. We think the Unoflow product is superior to the equivalent TEMA product. The Unoflow is fully marine-grade Stainless Steel AISI 316, while the TEMA is chrome-plated brass. The Unoflow quick connect is not compatible with the TEMA product. Don't risk your life by using inferior hookah hoses and quick couplings.
Hose Configuration: A hookah breathing air hose is normally set up with a Male quick coupling at the compressor end, and a self-sealing Female quick coupling at the diver end. Thus when a hose is disconnected the female end self-seals and prevents air loss.
Warning: Using general-purpose air hoses (e.g. as used with workshop compressors and found at hardware stores) that are not certified for breathing air can potentially damage your lungs and is in breach of Workplace Health and Safety regulations. The lining inside many air hoses often deteriorates with age, oil and heat, potentially releasing toxic particles straight into the users breathing air supply. Incorrect hose connector fittings are also often easily damaged and accidentally disconnected, thereby cutting off the operators breathing air supply.
