Catalina S40 Aluminium Cylinder | 5.7L | 207 bar | No Valve

Catalina S40 Aluminium Cylinder - 5.7L (40 cu ft) - 207 bar - Brushed Aluminium - DIN/Yoke valve. Catalina S40 (5.7 litre, 40 cubic foot), 207 bar, Aluminium Cylinder with DIN/K Valve. High-grade aluminium constructed especially to meet Australian safety standards. Negatively buoyant when empty. Rugged enough for rental gear or sport diving.

Because of its highly regarded buoyancy characteristics, the Catalina S40 aluminium cylinder is a popular choice as stage/pony tank(s) by technical divers. For longer, deeper dives they often use these cylinders to carry a Nitrox mix (e.g. EAN50, 50% oxygen) to accelerate their decompression on accent. Some have a second Catalina S40 stage cylinder with 100% oxygen for use on their final decompression stops. The Catalina S40 is a great cylinder for doing this.

Valves:
We supply a DIN to Yoke convertible, cross-flow valve as standard. The valves are made by Ocean Design. They are strong and reliable being made from really top quality materials. The valve regulator connection incorporates a threaded insert, which means it can equally be used for both INT bracket (Yoke) or DIN connection.

Note: If you require your cylinder unvalved, instead of a convertible DIN/Yoke valve, please specify when you order.

Valve Oxygen Cleaning:
The Catalina aluminium cylinders are supplied Oxygen (O2) clean, suitable for use with up to 100% oxygen. However, if you are planning to use the cylinder with Enriched Air Nitrox (Nitrox) mixes up to 100% oxygen, it's essential for the safety of the cylinder user and the person filling the cylinder that the valve be oxygen cleaned and prepared with special o-rings, seats, and grease designed for exposure to pure oxygen. The cylinder should then be banded with the familiar yellow and green Nitrox band/wrap/sticker, and an Oxygen Clean 'In Test' inspection sticker applied.
