11 mm is about a 34Fr.

Perfect for all types of enemas.
I have found this to be a great colon tube for easy, deep insertions.
I believe the low surface tension of the silicone vs rubber makes for the easier insertion.
This has become my main delivery colon tube/nozzle
I take a 2qt SSE for initial clean out.
Then fill the bag with 4 qts of water and with a slow flow advance the colon tube do the desired depth.
Every day is a little different, I never force insertions. Generally 3 to 4 feet of the colon ube gets inserted and
I take 3-3.5 quarts of water most often, 4 qts frequently.
