From Mares Press release:
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.

WASHINGTON, D.C. – The U.S. Consumer Product Safety Commission and Health Canada, in cooperation with the firm named below, today announced a voluntary recall of the following consumer product.

Name of Product: Mares Nemo Air Dive Computers
Units: About 600 in the United States, 140 in Canada and 15 in Puerto Rico
Distributor: Mares USA, of Boca Raton, Fla.
Hazard: An O-ring in the high pressure air connector can fail and leak air, causing a continuous but slow loss of breathing gas, which could require a diver to surface quickly, posing a drowning hazard to divers.
Incidents/Injuries: None reported.
Description: This recall involves the Mares Nemo Air Dive Computer, Nemo Air Dive Computer with Compass, Mares High Pressure Hose with Quick Connector for Nemo Air, and Quick Connector Assembly for Nemo Air. These computers have a digital screen which allows scuba divers to measure the time and depth of a dive and process other information to help divers determine safe dive times and ascent rates.

Remedy: Consumers should immediately stop using the recalled dive computer and connectors, and return the products to their authorized Mares dive shop for a free replacement O-ring connector assembly. The O-rings in some units may already have been replaced, but this recall requires replacing the metal quick connector fitting at the end of the high pressure air hose that holds the O-ring. Replacement connector assemblies have a groove machined around the middle of the fitting, but recalled units do not. All consumers should take their Nemo Air dive computers to a Mares dive shop to confirm whether this connector fitting has been replaced.
