IMO the MK25 is a piston first stage but is not environmentally sealed, not out of the box anyway....the mk25/s600 a very good breathing reg, it is environmentally seal piston.

The MK25s my dive buddy used were not environmentally sealed. The TIS system is about special coatings, etc. not environmental sealing.I thought the TIS system was environmentally sealing the piston?
It actually works fine in cold water. I have one and so do several people here in Alaska .
Will be testing out the gear for proper in Sipidan in a few weeks time.
Thanks for all the advice.
