The Cressi containers are manufactured according to high quality and safety standards. They are available in five different capacities: 5, 10, 12, 15, and 18 liters. The valves are produced by Cressi-sub and were the first easy-to-mount and dismount valves to appear on the market. The internal air channels have been carefully designed to ensure optimal performance, especially with the most powerful regulators. The valve design provides excellent grip, making it easier to open and close the tank. A brand new, exclusive slot system allows for quick recognition of whether the valve is open or closed (yellow = valve closed, red = valve open). The regulator connection features a threaded insert that can be used for both the INT fitting and the DIN connection. Since the valves are modular, it is easy to switch from a single connection valve to a dual connection valve and vice versa. The valves from Cressi-sub have successfully passed the stringent tests required by European standards and have received the prestigious CE certification.
