So I picked up some rubber pipe bits from 4Noggins (First order with them along with some pipe cleaners and shank brush, and the items arrived insanely fast by the way... wow fast)and the bits only fit on a two or three of my pipes. The stems on most my pipes are just too wide to be able to fit the bits on them. Is there such a thing as these rubber bits in a larger size? Or is that just the way it goes? If so, where can I find them? And if I can't find them, are there any home remedies that will serve the same purpose?
