Now that you have your end tips, take them with you and go to the hardware store (or plumbing supply store). You are looking for clear (may be other colors) tubing, usually sold in the plumbing section. There are many different types, you can choose what ever strikes your fancy, but keep in mind a few things.



1)You need it to be semi-flexible. If it isn't, your hookah may come tumbling down when you use the hose.



2)You might want to make sure the hose is non-toxic, food safe or water safe. I've seen some kool tubing in the store that after checking I wouldn't want to heat up and draw smoke thru.



3)Buy more than you think you'll need: at least, 36" up to 72", but the choice of length is up to you. You may need to alter the size to get better draw or trim the ends flush.



4)Make sure to test the end tips you have INSIDE the tubing you want. I most often find 1/2" OD (outside diameter) x 3/8" ID (inside diameter) tend to fit most, but check before cutting and buying.



Now at home, I tend to run hot tap water thru the hosing first. This cleans the inside and softens it up. If they came on a reel at the store, they are probably still be curved. The hot water softens it up so you can stretch the tubing straight. Either pull it between your hands, step on one end while pulling the other end upright, or get a second person to hold one end and stretch. Give it a minute or two, then let go. It should be somewhat straighter now.



Now check the end, are they flat? If not, use a razor blade to cut off some making a flat end. This way the tubing can fit flush against/into the end tips.
