The 6 Best Scuba Tanks, diving cylinder In 2023

The scuba tank, also known as a diving cylinder, is a vital component of essential equipment for divers. These cylinders securely contain compressed breathable air at significant pressures, enabling individuals to respire while submerged underwater. The scuba tank plays a pivotal role in facilitating the practice of scuba diving, integrating the “self-contained underwater breathing apparatus” (SCUBA) by providing the necessary air supply for divers’ respiratory needs.

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. It may also be used for surface-supplied diving, decompression gas, or emergency gas supply for surface-supplied diving or scuba diving. Cylinders provide gas to the diver through the demand valve of a diving regulator or the breathing loop of a diving rebreather.

Diving cylinders are usually manufactured from aluminum or steel alloys and are typically fitted with one of two common types of cylinder valves for filling and connection to the regulator. Other accessories, such as manifolds, cylinder bands, protective nets, boots, and carrying handles, may be provided. Depending on the application, various harness configurations may be used to hold the cylinder or cylinders while diving. Cylinders used for scuba typically have an internal volume (known as water capacity) of between 3 and 18 liters (0.11 and 0.64 cu ft) and a maximum working pressure rating from 184 to 300 bars (2,670 to 4,350 psi). Cylinders are also available in smaller sizes, such as 0.5, 1.5, and 2 liters. However, these are often used for inflation of surface marker buoys, drysuits, and buoyancy compensators rather than breathing. Scuba divers may dive with a single cylinder, a pair of similar cylinders, a central cylinder, and a more miniature “pony” cylinder carried on the diver’s back or clipped onto the harness at the sides. Paired cylinders may be manifolded together or independent. In some cases, more than two cylinders are needed.
