Zeagle F8 Regulator Yoke

Zeagle F8 Regulator Yoke

The Zeagle F8 pairs an environmentally sealed diaphragm first stage with an adjustable second stage. Its heat sink, anti-surge cover and durable valve materials suit divers who want a protected regulator platform with control over inhalation effort.

Features and benefits

• Balanced diaphragm first stage. The balanced mechanism regulates the supply to the second stage as cylinder pressure falls, helping keep the breathing response consistent through the dive.
• Dry environmental chamber. The sealed chamber keeps water and sediment away from the first-stage spring mechanism and supports resistance to freezing in cold water.
• 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.
• Balanced second stage. The balanced valve reduces the force needed to start airflow, while the inhalation knob lets you adjust the response.
• Heat exchange. The heat exchanger transfers warmth from the surrounding water to the valve area, helping counter the cooling that occurs as gas expands.
• Surge-deflecting cover. The front cover redirects moving water across the diaphragm, helping reduce unwanted valve opening when facing a current.
• Durable valve materials. The second-stage seat uses a silicone sealing surface supported by a metal insert, paired with a zirconium-plated inlet tube for wear and corrosion resistance.
• Flexible breathing hose. The braided hose bends readily around your equipment, helping reduce tension at the second-stage connection.
• Seat-saving design. When the regulator is depressurised, the dynamic orifice lifts away from the low-pressure seat. This reduces prolonged loading on the seat during storage.

Setup and compatibility

Connection: Yoke. Choose the fitting that matches your cylinder valve and its pressure rating.

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 Zeagle 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.
