Why divers choose carbon fiber cylinders

Carbon fiber cylinders offer a lighter profile than steel cylinders of similar capacity, which translates to less fatigue during long dives and easier handling on surface intervals and during travel. The combination of a carbon shell with a robust 6061 aluminum liner provides gas containment integrity while remaining compatible with standard regulators and hose assemblies. The 300 BAR rating supports longer bottom times with the same gas volume, making it a compelling option for open-water and technical dives when paired with proper training and equipment.

Use cases and care

Ideal for:

• Extended open-water dives and travel-friendly setups where weight matters
• Technical diving scenarios requiring high gas capacity in a compact form
• Divers who routinely fly with full cylinders and value efficient transport

Practical tips:

• Schedule hydrostatic tests every 3 years to maintain compliance and safety; track the last test date in your dive log.
• Inspect the M18×1.5 mouth and threads for wear before each dive; replace O-rings and regulators as needed.
• Store in a cool, dry location away from direct sunlight to protect the carbon fiber resin and liner.
• Have a qualified technician inspect the liner and end caps during service intervals—avoid DIY repairs.
