Oceanic has received isolated reports of DVT assemblies using a specific batch of DVT plungers extruding.
Testing and analysis indicates that this occurs when the First Stage is only partially depressurized prior to the removal from the cylinder. Back pressure from the instrument console could cause the DVT Plunger to extrude.
The affected DVT Plungers (PN 6903) entered the production process in November 2012 and contained softer molded material.
Testing indicates that earlier material and a new harder molded part eliminates any possibility of extrusion.
Oceanic urges all owners of Oceanic DVT type regulators that were purchased between Nov. 1, 2012 and June 10, 2013 to go online to verify if their serial number was affected.

If your serial number is listed on the website or your Oceanic DVT type regulator was serviced between Nov. 1, 2012 and May 14, 2013, take your regulator to your Oceanic Service Center to perform a parts retrofit at no charge to you.
No other Oceanic regulators were affected.
WARNING: DISCONTINUE USE of the Regulator First Stage until it receives a Retrofit. Only Authorized Oceanic Dealers and their trained service technicians can perform this Retrofit. Non-authorized persons who attempt the Retrofit procedure risk voiding the product’s warranty and rendering the product dangerously unsafe for SCUBA use.
