TUSA SS0007 Octopus/Safe Second Stage
The SS0007 is a compact alternate air source with a large purge button and Venturi lever. Its lightweight case keeps the second stage manageable, making it a practical companion to a compatible recreational regulator.
Features and benefits
- Venturi control. The lever changes airflow assistance inside the second stage. Use the pre-dive setting for surface handling and the dive setting as directed in the manual.
- 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.
- Compact case. The lightweight second-stage body reduces bulk when positioning the alternate in its holder.
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.
