TUSA S0011 Octopus Second Stage
The SS0011 Octopus brings TUSA’s enlarged purge and Ortho-Conscious mouthpiece to an alternate second stage. The yellow Miflex hose helps you identify the alternate air source while keeping the hose flexible for positioning and use.
Features and benefits
- Downstream demand valve. The SS0011 uses a conventional downstream valve for straightforward alternate-air operation.
- Accessible purge. The large purge button is easy to locate and press when clearing the second stage, including when wearing gloves.
- Mouthpiece comfort. The shaped silicone mouthpiece supports a comfortable, secure hold without adding unnecessary bulk at the mouth.
- Stainless steel faceplate. The metal cover protects the front of the second stage during everyday handling.
- Visible flexible hose. The yellow Miflex hose identifies the alternate supply and bends readily for stowage and deployment.
Setup and compatibility
Use as an alternate second stage in a compatible regulator system, with hose routing and stowage matched to your training and equipment.
Care, rinsing and storage
Clean this component as part of a complete, correctly assembled regulator system. After each dive, connect the assembled regulator to a scuba cylinder and open the valve to pressurise the system. Keep it pressurised while fully submerging the first stage, second stages and connected hoses in fresh water. This allows thorough cleaning of the exposed components and hoses while helping prevent water entering the internal air passages, where it can cause corrosion and damage. Keep the cylinder secure throughout cleaning.
For routine cleaning, Dive Gear Australia recommends Cressi Neoclean Wetsuit Wash Neoprene Cleaner 500 mL or Revivex Wetsuit Shampoo 10 oz to help remove salt, chlorine and everyday residue. Dilute according to the cleaner’s label, then rinse thoroughly with fresh water.
Keep the regulator pressurised throughout washing and rinsing. Lift it out of the water and dry the first stage and cylinder connection before closing the cylinder valve, releasing the pressure and disconnecting. Fit the clean, dry dust cap, then allow the regulator to dry in the shade. Store it with the hoses loosely curved, without sharp bends or tension.
Before each dive, inspect the mouthpiece, hoses and connections for wear or damage. Have your regulator serviced by an authorised TUSA technician at the interval specified in its manual, or sooner if it leaks, is damaged or its breathing performance changes. Leave internal adjustments and repairs to a qualified technician.
