  • The large venturi level is easy to locate and use and any time.
  • The XTX40 Octopus is pneumatically balanced.
  • Patented heat exchanger surrounds the valve mechanism, dissipating the cold.


TThe Apeks XTX40 mirrors the build quality and performance of the primary XTX40 2nd stage regulator. It’s pneumatically balanced design ensures it can deliver consistent, effortless breathing no matter your tank pressure.

Just like the XTX40 primary, the XTX40 Octopus is designed to handle extremely cold water, making it the ideal technical dive backup regulator. Highly visible accenting ensures that the XTX40 Octo is easy to see even when visibility is poor so you or your dive buddy can locate it in a difficult spot!
