We offer CCR Cylinder Sets configured for use with closed-circuit rebreathers. They are aluminum or steel, pre-configured for use as oxygen and diluent in your choice of sizes and valves. We ship your cylinder with the valve installed (domestic ground US only) and a few PSI pressure of oxygen compatible air necessary to keep the interior dry. During shipping the valve may loosen at the neck, so prior to the initial fill the valve should be made as tight as possible only by hand. The cylinders have a current month Visual Inspection Sticker; no re-inspection is necessary before filling. SCUBA Tanks must be hydrostatically tested every five years (60 months). Small cylinders are not frequently manufactured and typically have a factory hydro date between 6 and 12 months old, but not more than 24 months old.

> CCR Pair of AL Cylinders w/Modular Valves

These are a pair of brushed no-coat aluminum cylinders, pre-configured for rebreather use as oxygen and diluent in your choice of sizes. (Example AL-20 set pictured; see table for all cylinder choice specifications.) Both cylinders are oxygen clean with Thermo 200-Bar DIN modular oxygen compatible valves. The oxygen cylinder has a green handwheel and includes a green and white oxygen decal. The diluent cylinder has a black handwheel and includes a red and white diluent decal. The cylinders have a current month Visual Inspection Sticker; no re-inspection is necessary before filling.

The valves are configured by default as shown: Oxygen on divers right, outlets facing away from diver. Or if you prefer a different configuration, in the special instructions at checkout let us know what rebreather model with oxygen on divers left or right and valve outlets facing away from or toward the diver. If you decide to configure them differently both cylinders and valves are nitrox ready and decals are shipped loose, so you can change it yourself just by swapping the handwheels.

Advice for Traveling with Rebreather Cylinders

Regardless of the brand of rebreather it can be annoying to travel with cylinders because they are carefully examined by security personnel, and occasionally even confiscated. TSA says cylinders are allowed in checked baggage only if the cylinder has an open end. This means you must remove the valve and you must not plug the cylinder opening. Nothing should obscure the cylinder opening, not even just clear tape or a plastic bag. This also means the open cylinders that traveled with you in checked baggage are contaminated and no longer suitable for oxygen service. Have a plan for how you are going to have them oxygen cleaned at the destination. Consider taking the cylinders with you as carry-on baggage, where you can remove a travel cap yourself during security inspections. You may prefer to rent cylinders at the destination or ship the cylinders ahead by a package carrier where the cylinders may be sealed during transport.
