ProV1, OMG 25" long! When you finally got the whole thing in was part of it sticking out of your mouth?! :)
Would you tell me what it is called and provide a link to it? I MUST have one of those!! ;)
I don't know if you received an answer, but you can find what was described at siliconenozzles.com.
Look-up colon tubes. The one described, I think, was a CT-75fr colon tube (1-inch diameter). I have two, one at 36 inches and one at 54. The other ones I have are the CT-122fr (1.6 inches diameter).
They also have a huge assortment of nozzles in a variety of configurations. And many can be ordered without a center bore to be used as plugs.
See my albums for an idea of how big and how deep they get, as well as some of my toys.
