How do you connect surgical tubing?

Tiny zip ties work well. We slit both ends of the tubing, like a snake tongue, glued them with rubber cement, and put two tiny zip ties around the joint. It seems to be holding up.

I haven't yet tried this method, but I have tested the fit and it seems like it should work.


Take the two ends of the surgical tubing piece you want to join and roll them back on themselves a short distance (turn them inside out). Take a small piece of KOP pneumatic tubing and coat it in adhesive (not really sure what would stick best). Roll the surgical tubing over the pneumatic tubing and let the adhesive set.

When prototyping you may want to just put a wrap of masking tape around the pneumatic tubing. That breaks up the smooth surface of the pneumatic tubing and gives the surgical tubing something to grab on to.

It is also possible to order urethane tubing specifically designed to work as conveyor belt material. Check out the McMaster-Carr catalog on page 1018, or search CD for "round tubing". You'll find there is lots of discussion on the topic.

Your idea worked amazingly without any adhesive i'm sure it will work perfectly! Thank you!
