Microextrusions
Tubing that consistently holds tight tolerances
TekniPlex Healthcare can extrude medical tubing with outside diameters as small as 0.008 inches, less than 1 French size, and can achieve tolerances as low as +/- 0.0005 inches.
French Gauge | Diameter (mm) | Diameter (inches) |
1 | 0.33 | 0.013 |
1.5 | 0.5 | 0.02 |
2 | 0.67 | 0.026 |
3 | 1 | 0.039 |
4 | 1.35 | 0.053 |
5 | 1.67 | 0.066 |
6 | 2 | 0.079 |
*The metric measurement for catheter diameter (mm) can be determined by dividing the French size (Fr) by 3 (i.e., D (mm) = Fr/3). For example, a 3 Fr micro catheter has a diameter of 1 mm. Increasing French sizes correspond to larger diameters).
