Medical Heat Shrink Tubing

Worlds thinnest, smallest, strongest heat shrink tubing

Nordson MEDICAL is known for having the thinnest, smallest, and strongest medical tubing in the world. We are the exclusive supplier of polyethylene terephthalate (PET) medical heat shrink tubing, which uses a proprietary process developed by Vention Medical / Advanced Polymers.

Thinnest, Yet Strongest

PET medical heat shrink tubing combines incredible strength and durability with extraordinarily thin walls. In addition, PET heat shrink tubing can be "drawn down" to reduce tube diameter by up to 70% while maintaining an ultrathin-wall and ultrahigh-strength tube.
