Apeks EVX TUNGSTEN Second Stage

Apeks EVX TUNGSTEN Second Stage

Add the EVX Tungsten second stage to a compatible regulator configuration for its laminar-flow valve and progressive purge. Reversible hose routing and interchangeable exhaust options let an authorised technician arrange the setup around your preferred equipment layout.

This listing is for the separate second stage, for use in a compatible regulator assembly.

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.
• Laminar-flow valve. The EVX valve is designed to guide gas smoothly through the second stage, reducing turbulence in the breathing path.
• Inhalation-effort adjustment. The adjustment knob lets you change the effort needed to start a breath, so you can tune the response within the regulator’s operating range.
• 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.
• Progressive purge. The purge responds to how firmly you press it, giving you control over the flow used to clear the second stage.
• Reversible hose routing. An authorised technician can configure the second stage for left- or right-hand hose entry to suit your equipment layout.
• Interchangeable exhaust. The exhaust options let you choose a compact layout or wider bubble diversion to suit your diving and field of view.
• 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.
• Tungsten finish. The dark PVD coating adds a hard protective finish to exposed metal surfaces, helping resist wear during regular use.

Setup and compatibility

This is a separate regulator component. Pair it with a compatible first or second stage and the required hose; the complete assembly must be configured and checked by a qualified technician.

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 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.
