A diving cylinder, scuba tank or diving tank is a gas cylinder used to store and transport the high pressure breathing gas required by a scuba set.
Diving cylinders are usually manufactured from aluminium or steel alloys, and are normally fitted with one of two common types of cylinder valve for filling and connection to the regulator.
Many jurisdictions have regulations that govern the filling, recording of contents, and labelling for diving cylinders.
Periodic inspection and testing of cylinders is often obligatory to ensure the safety of operators of filling stations.
The selection of an appropriate set of diving cylinders for a diving operation is based on the amount of gas required to safely complete the dive.
Diving cylinders are most commonly filled with air, but because the main components of air can cause problems when breathed underwater at higher ambient pressure, divers may choose to breathe from cylinders filled with mixtures of gases other than air.
