Cressi yellow low-pressure octopus hose
Replace the matching alternate-air-source hose with Cressi part HZ730225. This 100 cm yellow low-pressure hose connects a compatible regulator first stage and octopus second stage, with the yellow exterior making the alternate hose easy to identify in your setup.
It is useful when renewing a worn or damaged hose, or when a technician is assembling a compatible regulator configuration. Choose the hose length to suit the intended routing and use of the alternate air source.
Fitting and inspection
Have a qualified technician confirm both end connections, fit the hose and pressure-check the completed regulator assembly. Before diving, inspect the hose and fittings for wear or damage and confirm that routing allows the required movement without sharp bends or strain. Do not continue using a hose that is leaking or damaged.
