I was always worried about my Subal type 3 ports coming off underwater, so I switched to Nauticam.  Now, I find that taking ports off of my Nauticam 7D housing is difficult, and requires a lot of force.  Much harder yet is separating the zen minidome from the extension ring.  I have had to soak them in very hot water, and then use all my strength to rotate them and pull them apart. (Yes, I did unlock them). Now, I cannot get them apart at all. I would have much preferred the easy removal with Subal to my present situation.

 

All comments appreciated.

Unfortunately, it will not help you, but ...

I do not have the Zen Minidome, but a Zen big dome.

I find that it easily comes off from the extension ring.

 

You need to move it back a little bit from the end.

Are you sure you are using the right size (thickness) o-rings? I had difficulties putting a Subal extension ring and port together until I used a slightly thinner o-ring.

there is a port-lock on Subal's newer housing now and it is a really good solution. But since you already changed to another brand swichting back may not be an option....

Sounds like a reasonable reason.

 

I once mistook the Port O-ring and the O-ring for the Drysuit Glove system.

The Port was like a rock, but I got wet and cold hands  :dance:

Luckily enough it was not the pther way around!

I ordered the correct o ring, which is actually made by Sea&Sea, not Nauticam.  Thank you for your suggestions.

Hi,

 

Did you check up whick one it is? I am so far having the Nauticam as a back up.

I am a bit confused on which of the Sea&Sea to order!

I cannot recall the specific oring now, but the information is readily available on Reef Photo's web site.  The Nauticam port orings are much thicker.  I would not even consider using one.  E_Viking may have solved this problem.  if you turn it fully counter clockwise, it locks again.  Backing off just a little frees it up.  I was not quite sure what he meant, but stopped in Ocean Optical, and Jack Connick showed me in Person.  Many Thanks.
