Update on Pressed Steel Tanks (PST)

This is an update on Pressed Steel Tanks (PST) and should be shared with anyone who owns a PST tank and also all dive stores servicing or filling these tanks. 

 

DEMA has received numerous calls regarding the impending expiration of the Special Permit from the US Department of transportation (DOT) under which Pressed Steel Tanks were produced.  The Special Permit was issued in 2011 and expires on January 31, 2015.

 

DEMA has been in contact with the DOT and, working with Professional Scuba Inspectors (www.psicylinders.com), has obtained a copy of the NEW Special Permit which expires in 2018.  This means that all PST tanks with the neck stamped with SP9791 or E9791 which are visually inspected and within hydrostatic test date are valid and may be filled (or hydrostatically tested as needed).  

 

For more information, see this Special Permit on DEMA’s website.
