Steel 110 Valve Question

[devildog12210]

Hey Guys,

I originally posted this in the Basic Suba Discussions section but now realize it is more applicable to this section. Any help would be appreciated.

I am in the aviation industry and I have a few steel 110s that I can grab that we are no longer able to use for aviation purposes. They have the DOT head stamp and have had their regular hydros. Neck reads DOT-3HT3000 and REE110.3. The problem I am running into is they were made for a 1.5" valve. I haven't found anything as far as a yoke or din valve that goes that big. Am I just out of luck here or do I have another option to use these tanks for scuba?

Thanks!
