A dive friend of mine gave me a Conshelf SE2 reg set to verify because it was free flowing the main second.
The first test was to messure the IP. It was too high, reaching 14 BAR when the main second starts to free flow.
After dissasembly I could see that the only o-ring inside was too stiff and cracked. I guess this o-ring had more than 15 years.
Going to the point, the Conshelf service manual states that to assembly back the HP internals it's needed a special tool "High-pressure block guide (USD P/N III0-00)". It's possible to assembly the internals without that tool, but it's a nightmare.
So, impossible to buy that tool anywhere here, brain and hands to the CAD and I designed and 3D printed the tool.
Attached the STL files of the two parts.
