Mares has discovered a quality issue involving the O-ring assembly of the Nemo Air Quick Connector.
Under certain circumstances, the O-ring can fail and cause a slow leak of breathing gas through the Quick Connector, which could require a diver to surface quickly and face possible risk of injury or running out of air.
Any air leak resulting from an O-ring failure would be slow, because these fittings are designed to the EN250 standard, which requires a very small (0.3mm) opening in the high-pressure hose fitting, but we nevertheless take this issue seriously and intend to correct all affected units.
The O-rings in some units may have been replaced in an earlier service campaign, but this recall requires replacing the entire metal quick connector female fitting at the end of the high pressure air hose that holds the O-ring (new Mares part no. 44200829). Replacement connector assemblies have a groove machined around the middle of the fitting, but recalled units do not.
ALL CONSUMERS SHOULD STOP USING ANY NEMO AIR DIVE COMPUTER, AND ALL RETAILERS SHOULD REMOVE THESE UNITS FROM DISTRIBUTION , UNTIL THEY HAVE BEEN INSPECTED AND REPAIRED BY AN AUTHORIZED MARES DEALER / SERVICE CENTER.
Affected product codes are:
414158 DIVE COMPUTER NEMO AIR
414159 DIVE COMPUTER NEMO AIR W/COMPASS
44200771 HP HOSE W/QUICK CONNECTOR NEMO AIR
44200770 QUICK CONNECTOR ASSY. FEMALE NEMO AIR
