Product Overview

About This Product

The Catalina S19 is a compact 2.7 L, 207 bar aluminium cylinder commonly compared for pony or reserve-cylinder setups. It provides a clear capacity step above the smaller S13 while remaining below the S40.

Compare the S19 with the S13 when compact size matters, or with the S40 when additional capacity is the priority.

Choose With DIN/K Valve if you need the valve supplied with the cylinder, or Without Valve if you only require the cylinder body.

Scuba cylinders are dispatched unassembled for shipping. If you select the valve-equipped version, the DIN/K valve is included but packed separately and is not fitted to the cylinder for transit.
