USP Class VI and ISO 10993 tested tubing, platinum-cured in a controlled area and lot-traced from compound to packed carton. Bores from 0.5 mm for catheter and pump duty.
A medical tube programme lives or dies on documentation. Which lot of compound went into which run, what the extractables profile looks like, whether the change you made to the die last month was communicated to the customer before it shipped. We run the extrusion and the record keeping as one process, because a tube without a traceable lot number is not a medical component.
Tubing is produced in a controlled area with filtered air and dedicated tooling, then packed double-bagged. Bores below 2 mm are drawn on a mandrel to hold concentricity, which is where most thin medical tube fails: an off-centre bore changes the pump stroke and the dose with it.
Same compound family, different construction. Mixing two options on one order is common and usually cheaper than splitting the purchase.
Tight tolerance bore for volumetric dosing
Soft, kink-resistant, non-collapsing wall
2–4 lumens for combined delivery and sensing
High tear strength, thin wall, radiopaque option
Dosing lines where bore tolerance drives the delivered volume.
Blood and dialysate paths; verified haemocompatibility data.
Soft walls that do not collapse under suction.
Breathing circuits, 22 mm and custom connectors.
Low extractables for injectable contact.
Single-use sets, EO sterilisable, double-bagged.
Concentricity matters more than wall tolerance on sub-2 mm bore. We hold TIR to 0.08 mm on the drawn sizes and supply a cross-section measurement with the first article.

Bore, wall, concentricity, sterilisation method and the standard you are designing to. We come back with a compound recommendation, a dimension sheet and the documentation you will need for your technical file.
