The Caterpillar is a unique nozzle that can function not only as an Enema Nozzle but as a Retention style Colon Nozzle as well. Its twelve-barrel-style ribs can be inserted into any position and comfortably held in place with the small valley between each enlarged barrel-style rib. The multiple ribs and sensory valleys in this 16" overall length nozzle are 1.5" and 1.1", respectively, except for the final retention valley at the flange, being 0.9" in diameter. The safety flange is 2" in diameter. It is available with a 1/4" or 5/16" internal bore or as a solid piece without a bore.
The overall length of this nozzle is 16 inches, including the flanged base, insertable length is approximately 15". The initial diameter at the tip is approximately 1", and the first enlarged rib is 1.4".
This is a really nice nozzle for articulating its way up through the rectum and into the lower sigmoid colon allowing for the deposition of the enema fluid to gently and easily flow into the transverse and higher colon segments for a complete filling experience.
This piece is not meant to function as a full retention style nozzle but will enhance your ability to retain the enema solution after it has been administered. Overall, it is a very pleasurable sensory enhancing nozzle as well.
