How to conjoin surgical tubing?

[Ryan_Davis]

We cannot tie the tubing so we neither a step by step on how to melt or glue surgical tubing. Thank you very much in advance, Eastridge Robotics.

You will destroy the tubing if you try to melt it. There is no glue that is both strong enough and flexible enough to bond with acceptable integrity to the tubing.

Why can't you tie it ?

I usually cut (or stretch) the tubing so that the ends go past each other and then put two zip ties around both ends and cinch them together. Just be careful, some zip ties can cut the surgical tubing when tightened too much.

we have used hose clamps in the past, i have always thought that if you could inflate the surgical tubing with compressed air, then put one end inside the other and let the air out it would make a strong bond.

Thank you both very much, we have decided to forgo the use of surgical tubing.

Someone else may find this useful...
Cut a short length of pneumatic tubing (2-4 inches will do, longer will make a better bond) and slide both ends of the surgical tubing over it. It's surprisingly strong, although I can't vouch for it's performance under very high loads or over a long period of time.

i got a better idea, get heat-shrink that just fits over the tube before shrunk, then shrink it.

A smaller diameter length of surgical tubing can be inserted into larger tubing, but it is very difficult. The upside is that it is just as difficult if not harder to remove (this is only a good thing if you don't have to undo the connection once it has been made).

Take a look at a wrist rocket slingshot and see how the sugical tubing is attached to the slingshot.

Danger: Do NOT use lubricant to slide the tubing on. It may slide off and hit someone in the eye.

Would a solvent (such as isopropyl alcohol) work? It should lubricate when its wet, then evaporate quickly afterwards. I believe its what's used to re-grip golf clubs.
