[Solved] Help Identifying a DIN First-Stage Regulator 4port

[foxx]

Hi,

I’m trying to identify a first-stage regulator we use at our diving club. Unfortunately, it has no visible branding or logo, and we’re unsure which service kit it requires. We’d prefer to identify it first before opening it to avoid unnecessary risks or complications.

• Ports: 4 ports in total – 2 LP ports for second stages, 1 HP port for the pressure gauge, and 1 LP port for the BCD inflator.
• Markings: The regulator has the following markings:
  • CE 0474 (indicating compliance with European standards).
  • L.I.77H 04 0593
• Design: It looks similar to a Cressi AC2 or Scubapro MK2, but it is not this exact model.

I wanna guess (shot in the dark) seeman sub (I think I saw something similar on a classified a while back, iirc)
I’ll check their catalog and come back to you

Ok, it’s not, it’s a C30 from Coltri — the outer “orings” and the 0474 were the hints

This was hard to figure out since it’s not easy to find information about Coltri Sub regulators online. I’m very grateful for your help!

Silver lining, the manual described the oring sizes, so you can source them from generic sources if the service kit isn’t available to you
The HP seat… different story, long shot the mk2 (not evo) seat might work

Good luck getting it back to shape, happy diving
