I use these and I think (must check) I have one extra without the tube. If you do not mind to pay postage from the Netherlands . . . On the two siphons I use I have replaced the tubes with silicon tubes. That way I could give them the length I needed, and I attached a pvc connecting piece that clicks onto a similar piece on the tab. The silicon tubes I found are transparent and more flexible (softer) than what Kodak supplied. Much easier to work with and safer too as I find Kodak's connecting piece a little flimsy . . .
