Aqua Lung is recalling about 6,000 Titan DIN 1st Stage Scuba Regulators and Titan/Conshelf DIN Scuba Adaptors. Over-tightening of the DIN retainer by a technician during installation can result in the retainer breaking under pressure, a rapid escape of air from the scuba cylinder, and the regulator detaching from the scuba cylinder.

This poses a drowning hazard to divers. 

The firm has received one report of a DIN retainer breaking under pressure. No injuries have been reported. 

The recalled regulators have a brass DIN retainer manufactured prior to June 2006. The recalled Aqua Lung Titan Din 1st Stage regulators have serial numbers lower than 6062501 stamped on the side of the regulator’s body. Recalled Titan/Conshelf DIN adaptors are marked “300 BAR MAX” on the side of the part. DIN adaptors marked “300 BAR MAXI” are not included in this recall. 

The regulators, made in France, were sold by authorized Aqua Lung dealers nationwide from January 1997 through September 2008 for about US$300 to US$450 for the scuba regulators or $70 for DIN adaptors sold separately. 

Consumers should immediately stop using the recalled diving regulators and DIN adaptors and return them to any authorized Aqua Lung dealer for a free replacement DIN retainer. For additional information, contact Aqua Lung toll-free at (877) 253-3483 between 8 a.m. and 5 p.m. PT Monday through Friday, or visit the firm’s Web site at www.aqualung.com. 

The recall is being conducted in cooperation with the U.S. Consumer Product Safety Commission (CPSC).
