SRU-40B/P HABD - do they need hydro and VIP?

[crzyfish]

Hey, folks! I haven't been around for years and just trying to get back to the swing of things.

I was doing some inventory of the gear I had and ran across two SRU-40B/P HABD in my possession. Both still have air in them. Do I need these Hydro and VIP? I bought these years ago and only filled them with my tank but never took them into the ocean. Are they worth much?

They're 3000psi and only 1.5CF. They look like this: (had to borrow a pic)

I believe this statement is correct: A cylinder that is less than two feet in length and less than two inches in diameter and has a working pressure of less than 2000 psi does not need a Hydrostatic Test.

Given the WP is 3000psi these cylinders do need to be requalified.

So little room to stamp a new hydro date! I think a VIP sticker would effective become a tank wrap, too.

I've got bunch of tanks to re-hydro, maybe they'll give me a volume discount or throw in the re-cert for the little ones. Do many shop re-hydro these tiny tanks, similar to the Spare Air ones? I like to tell people the pony isn't for me, it's for the people who used up THEIR air.

They should, and if you have multipule tanks im sure you can get them to do it for free
