all of my different cc's irrigators fit from those that hold up to 80 cc's to the very small,pointed ones I've gotten from dental offices, the Weber and Judd was only 29 fr, even smaller, so I'm not sure what you're using, I think all of mine came from hospital stays or whatever I saw online from the medical supply houses, I had no idea there were different sizes, some were pointy, some not. Perhaps you need to ask your medical supply house. All have fit easily.
