Scubapro USA, a division of Johnson Outdoors, and the CPSC are recalling about 48,500 MK20 first stage regulators due to potential damage that can be caused during servicing.

The company stated that the Yoke or Din could cause the regulator to crack if over-tightened. If this occurs during a dive, air supply could be interrupted. No injuries or underwater incidents have been reported. Scubapro USA has received eight reports of units that failed after being serviced.

The regulators were sold at Authorized Scubapro dealers nationwide from January 1996 through December 2001 for about $260.

Scubapro USA has been providing a service upgrade kit via the authorized dealer network since May 2005 which contains a Yoke or Din retainer that prohibits over-tightening during annual service. Consumers can easily identify if the service upgrade has been completed by counting the vents on the plastic saddle located on the regulator. If the service upgrade has not been completed, the consumer should bring the regulator to any authorized Scubapro dealer to have the service upgrade completed free of charge.
