Multi-Durometer Coil Reinforced Tubing
Coil reinforcement on multi-durometer medical tubing improves its pressure holding capability without increasing its stiffness as a harder material would. Coil reinforcement also improves kink resistance and provides greater hoop strength.
Duke Extrusion offers a wide range of specialty stock tubing products. We provide the industry’s shortest lead times for custom multi-durometer coil reinforced medical grade tubing for catheter delivery systems. Standard sizes are available, from 2 to 24 French.
We can also create custom coil reinforced tubing to match your unique requirements. Numerous coil materials are available, including aramid fiber and PET. Coil pitch can be modified to your exact specifications: coils with high pics per inch (PPI) provide greater flexibility, while lower PPI offers increased stiffness. Our custom multi-durometer coil reinforced medical tubing is available with up to 7 individual durometer segments, though 3-5 are often sufficient for most applications.
This specialty tubing is also available with PTFE liners for improved interior lubricity.
