Oh, it will be two of these: https://www.macartney.com/what-we-offer/systems-and-products/connectors/subconn/subconn-micro-circular-series/subconn-micro-circular-2-3-4-5-6-and-8-contacts-and-g2-2-3-and-4-contacts/
The 'MCBH?F' variety.

Obviously I have no idea of the wall sections, but can't imagine...
As a side note, there are companies that design subsea housings similar to what I'm aiming for:

I would like to understand the theoretical side of defining the wall thickness before I proceed to FEA...
Yes, I can see that since the process involves using their charts. Is my application definitely relevant for use with ASME Section VIII Div 1? I feel like it is, but it appears they've not written this spec for subsea applications specifically.
I don't really have an objection tbh, you raise a...
There will be ports on the top and electrical connectors, therefore, not suitable for spherical design.
Bracing is a possibility, but internal space is very limited and I'm not sure how much I could add here (if any) as well as not knowing how I could calculate stresses involved.
As a side...
I’m designing a subsea sensor that will go to a max depth of 600 m (6 MPa/60 bar). In a simple model, it will be made of a pressure housing cylinder and two end caps, all grade 5 titanium. Some geometry is attached.
I’m looking for advice on how to calculate the thickness of the...
I would like to have the entire assembly captive so that there's no chance of losing the parts (why there's a shoulder and a dowel pin either side of the threaded part). The centre piece must align with the block so that can't be threaded.
You've sparked one idea: move the piston o-ring from...
I am working on a design where I have a block which has a cap assembly fitted to it - see images attached.
The cap assembly is constructed of:
- Main body with two holes through (flowing water in and out)
- Locking ring with a threaded outside, grooves for tightening by hand and two o-rings...
When I say block, I mean the entire metal section. The yellow section you've highlighted - is this distance something I should reduce in order to get faster temperature change?
I want to hold the temperature constant and then run experiments on the sample at that temperature. When the temp is...
My apologies, my initial diagram was an early concept simplification - see attached for a better reason for having a glass tube. Essentially, all four bores are for optical purposes, with LEDs behind them. We had a previous product using the glass tube, but without the need for thermal control...
Sorry, the design was a simplification. The reason it is a tube is that at various angles in the block, there will be bores machines with light emitting into the glass tube, therefore, the block cannot be in a membrane or balloon. For this example, the seawater sample is only in the position...
