Our BTS Sidemount Cylinders are available either as a set or as single cylinders, in three sizes: 80 CUF, 7L, and 40 CUF.

Each aluminum sidemount cylinder comes equipped with either a left-hand or right-hand expandable valve, making them ideal for sidemount divers or those who prefer to carry stage cylinders on both sides.

You can find the detailed specifications for each cylinder size below to help you choose the perfect match.

All cylinders are available as a set or individually for the left or right side.
