Source for o-ring to fit i200c

[MudBug]

Does anyone have a source for the o-ring to fit a AquaLung i200C dive computer?
I found the measurements on another post on this board but am having difficulty finding a vendor online with that size.

The size is 27.5mm(ID) x 1.2mm (cs)

Thank you.

Wondering the same thing. 27.5 is about 1"
We also need to know the correct durometer .
My guess is that this is a custom oring.

Durometer is 70.
As competitive as this market is, I'm willing to bet the designers wanted something off the shelf in order to keep costs down. Custom costs.

I may have to break out my micrometer and pop the back off of my AquaLung i200C and make some measurements.
