Apeks XL4 OCEA Octopus With Hose
Keep the alternate air source in your OCEA setup compact and accessible. The XL4 OCEA Octopus combines a Venturi lever and Comfo-Bite mouthpiece with the supplied hose, giving you a matching component for a compatible regulator configuration.
Features and benefits
- Balanced second stage. Pneumatic balancing reduces the force needed to open the demand valve, helping the second stage respond smoothly as you inhale.
- 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.
- Comfo-Bite mouthpiece. The silicone palate bridge supports the second stage with less need to clench your jaw, which can make longer dives more comfortable.
- Compact alternate. The small housing keeps the alternate manageable when arranged in its holder, with the supplied hose routed for your trained donation procedure.
- Accessible purge. The large purge button is easy to locate and press when clearing the second stage, including when wearing gloves.
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
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 Apeks 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.
