Joining Surgical Tubing
1. Insert dowel slightly larger than the inside diameter into one end of the tubing about 1.5 inches.
2. Fold back the tubing over itself for about an inch.
3. Remove dowel.
4. Apply contact cement all around the folded back end and about an inch on the other end of the tubing.
5. Allow cement to dry until it is tacky to the touch.
6. Butt the two sides together and unfold the folded end over the nonfolded end.
7. Allow to dry and test.
8. If you need additional strength, you can add some stitching with needle and thread.

Hope this helps.
