Tank Fill Notices
Underwater Adventures reserves the right decline filling any tank which we deem may be unsafe or is not compliant with DOT regulations. What are the affected cylinders and which aluminum tanks are affected? Specifically the alloy 6351 affected. (Steel cylinders are not affected).
Here is the official advisory that was published by DOT:
The following summary for scuba cylinders are known defective:
All Walter Kidde DOT-3AL cylinders, of which production ceased in January 1990, are made of alloy 6351-T6. Cliff Impact DOT-3AL cylinders
were made from alloy 6351-T6 before July 1990, at which time Cliff Impact changed to alloy 6061-T6.
Catalina Cylinders did not produce any DOT-3AL cylinders from alloy 6351-T6; therefore, cylinders manufactured by Catalina are not subject to this notice. Until determined otherwise, any DOT-3AL or DOT-E 7235 cylinder should be assumed to be made of alloy 6351-T6, if it was:
1. Manufactured by Luxfer USA before the applicable date listed in
the chart below.
2. Manufactured by Cliff-Impact before July 1990;
3. Manufactured by any other company in the United States,
excluding Catalina, before February 1990; or
4. Manufactured outside the United States.
Lets focus on cylinders made by Luxfer as they are the most predominate scuba cylinder made with AL6351:
30 and 63 cu. ft…………………………S30, S63………mfg date 5-88
40 cu. ft…………………………………….S40………………mfg date 6-88
50 and 92 cu. ft…………………………S50, S92………mfg date 4-88
72 and 100 cu. ft……………………….S72, S100…….mfg date 8-87
80 cu. ft…………………………………….S80………………mfg date 1-88
80.8 cu. ft………………………………….S80.8………….. mfg date 5-87
By quickly scanning one can see that by July of 1988 Luxfer had quit making cylinders using AL 6351 and had fully switched over to AL6061. As importantly, given that the vast majority of aluminum scuba cylinders in use are AL80 for the most part one could “safely” say that any Luxfer AL80 made with a hydro year of 1988 were made using AL6061.
