does anyone have an OTW cylinder instruction manual

[SVilling]

Hello!
I am looking at replacing or getting spare orings for an OTW cylinder and was wondering if there is a 'users manual' available, please?

Thanks all!

They're just bog standard rings. What diameter is the cylinder 11cm?

Looks like it. Best estimate on the orings there are 100ID and 106OD, but I can’t find that exact size easily, maybe making 100ID and 2.65mm cross section the most likely? Also used AS007 to replace water sensor orings.
