PVC Medical Tube Extrusion Line 2–12 mm with X-Ray Line – Radiopaque Medical Tubing Line

Overview
The Φ45 mm Medical Tube with Blue X-Ray Line Extrusion Line is engineered for the production of soft medical-grade PVC tubing
with outer diameters from 2 to 12 mm, incorporating a blue radiopaque stripe for X-ray visibility.
Radiopaque lines are widely used in medical drainage and infusion tubing so that clinicians can track tube position under X-ray and fluoroscopy.

Typical Applications
• Wound drainage tubes with X-ray line.
• Suction and irrigation tubing.
• Respiratory and oxygen tubing.
• General-purpose medical device tubing where X-ray traceability is required.
