How to get 38's hydro'ed?

[SubseaSports]

I have a set of USN 38's that I need to finish cleaning before hydro and am already asking around about this.
Local hydro shop will not test the tanks with a bushing (he doesn't have a larger fitting either).
Not many hydro shops around here to help to begin with (I use an app to search). 'Here' is North Florida.
How did you get your set hydro'ed?


FAQ answers : I plan on picking up hp stainless bushings for my own piece of mind and replace the existing ones. Fills aren't and issue as I will fill these myself.

Speak with your local fire equipment dealers, you may have to go to Gainesville or Jacksonville.

Also, I do not recommend stainless bushings, or steel ones for that matter. Look for a Cajon or Parker 3000 psi rated brass bushing. They are a bit softer and I find they seal better.

Any hydro shop that services CO2 fire extinguishers should be able to do it.
