Great regs. I've rebuilt both. Best offer I've seen all week!

It's the Farallon gauge I like: it an SPG on one side and a depth gauge on the other. I've got one on my HW Scubair-II  JB |

These came with 2 round-bottom AMF aluminum cylinders. I couldn't find the exemption number on the DOT list, so they're not hydroable. Any interest?
Good Dives,

Same deal on these tanks. Of course, these won't fit in a flat rate box. Have any of you seen 2700 psi aluminum cylinders? Good Dives, Charlie  IMG_1977 by Charlie will, on Flickr |

Being curious about the 2700 psi aluminum cylinders, I had a look for information. The special permit 6576 Kaiser cylinder (brand name AMF) has a 2,700 psig service pressure and a somewhat rounded (beveled) bottom. Unfortunately for owners of Kaiser SP6576, these cylinders must be removed from service in the US as those permits expired by 1979. A special grandfather clause allows their use in Canada. |

If by chance the AL 2700 psi tanks do not find a home, I am certainly interested in the tank valves.

I'm sending the cylinders to a PSI Trainer as examples of what not to certify. I'll see if I can find the valves. I think they are Voit valves made of anodized aluminum.
Good Dives,

Glad there is a good use for the tanks. The compact design of the valves is what caught my eye, could be a nice option to have on hand.
Thanks for the reply!

If I may ask, what’s wrong with these aluminum tanks? Are they made from the bad alloy used in the 70s? Wasn’t it only Luxfer tanks affected? Interesting that they are 2700 PSI with a round bottom.

Sustained load cracking occasionally develops in 6351 aluminum alloy high-pressure cylinders. US manufacturers that used 6351 alloy included Luxfer Gas Cylinders (made prior to May 31, 1988), Walter Kidde, Cliff Impact, Norris Industries (SP6688) and Kaiser (SP6576).
