Argonaut Kraken exhaust can valve upgrade
The Argonaut Kraken double-hose regulator has encountered a specific issue where the internal exhaust valve can adhere to the main diaphragm. This adhesion effectively locks the regulator, preventing air delivery. While this problem typically arises during pre-dive preparations—such as on the boat—it can be particularly frustrating, as it may delay or prevent the start of a dive .
Solution: Upgraded Silicone Exhaust Valve with Stand-Off
To address this issue, a specially designed replacement exhaust valve has been developed. Crafted from food-grade silicone, this valve features an integrated stand-off that prevents it from sticking to the diaphragm, thereby eliminating the risk of regulator lock-up .
Installation Instructions:
-
Remove the Original Valve: Carefully extract the existing exhaust valve from the regulator.
-
Lubricate the New Valve: Apply a small amount of hand sanitizer to the stem of the new valve. This acts as a lubricant to facilitate insertion.
-
Install the New Valve: Gently pull the lubricated stem into place within the regulator housing.
This straightforward installation process ensures that divers can quickly and effectively upgrade their equipment to prevent potential issues.
Additional Insights
Some divers have reported that the valve sticking issue can also occur underwater, leading to flooding of the exhaust loop. In certain cases, divers have implemented alternative solutions, such as modifying the diaphragm with a silicone “X” pattern to prevent adhesion .
Availability
The upgraded silicone exhaust valve with stand-off is available for purchase through specialized diving equipment retailers. For instance, Vintage Double Hose offers this replacement part, but availability may be limited, so it’s advisable to order promptly.
