GC3 Flowstop

GC3 - FLOWSTOP

The Flowstop is a high-performance in-line gas isolator. Simply slide the knurled collar forwards in the direction of the gas flow to instantly cut off the gas supply. The Flow-Stop features large bore feed holes that are recessed to reduce O-ring wear.

The Flowstop is perfect for isolating your ADV:

• To shut-off gas supply in case of free-flow
• To disable the ADV at the bottom stage of the dive to manually control loop volume if preferred - for example, if diving a saw-tooth profile
• To disable the ADV at the deco stage of the dive if preferred. This may be to avoid potential dilution of the deco mix by ADV injection if the diver is rising and falling with a swell

IMPORTANT NOTE:  The GC3 FLOWSTOP is NOT SUITABLE for use within an Open Circuit (OC) gas delivery system. The GC3 FLOWSTOP MUST NOT be used in-line with the AP Gas Connection System (GCS) when it is used for OC bailout or OC gas-switching, as it will significantly decrease breathing performance.
