Bi-colour & Radiopaque Silicone Tubing
Bi-colour Silicone Tubing Manufacturer
Suconvey manufactures bi-colour silicone tubing, including radiopaque silicone tubes, engineered for industries that need high-visibility fluid lines with enhanced detectability.
Our tubing combines the flexibility and performance of silicone rubber with clear visual differentiation or X-ray detectability, making it ideal for medical, food, pharmaceutical and industrial applications where identification, safety and traceability are essential.
Bi-Colour Silicone Tubing
Bi-Colour silicone tubing is a dual-layer or dual-colour tube where two distinct colours are combined in one wall. This design helps operators quickly differentiate lines by media type, service purpose, or safety classification on complex assemblies.
Radiopaque silicone tubing contains embedded radiopaque additives that make the tubing clearly visible under X-ray or other imaging. This is widely used in sectors where visibility under imaging is critical, such as medical device assembly and pharmaceutical inspection.
Suconvey’s bi-colour tubing may be produced with radiopaque options, custom colour combinations, and advanced constructions to meet your identification, traceability and regulatory demands.

Why Combined Bi-Colour & Radiopaque Tubing?
In many applications, designers face two persistent challenges:
- Line identification → Operators and technicians must quickly distinguish fluid paths on complex machines — especially in medical and multi-channel processing lines.
- Imaging detectability → In devices or inspection processes, tubing must be visible under X-ray/CT/fluoroscopy for safety or quality control.
Our solution is to offer bi-colour tubing that also incorporates radiopaque markers — giving you the best of both worlds:
- colour-coded lines for everyday handling
- radiopaque visibility for imaging and inspection
This is particularly valuable in regulated environments like medical device assemblies, pharmaceutical filling systems, and high-speed food automation lines.

Packaging & Shipping Information
To protect the product during global transportation and storage, we apply export-grade packaging and provide flexible shipping solutions.
Pre-Shipment Inspection
Each batch is inspected before packaging to confirm hardness, thickness, surface condition, and visual uniformity. Batch codes are recorded and compliance documentation may be provided when required for regulatory purposes.
Packaging Method
Silicone tubes are wrapped with protective film to prevent dust, moisture, and surface damage. Several rolls are placed into reinforced cartons, which are then secured on fumigation-free pallets using straps and stretch film.
Shipment Options
We regularly ship to customers in Europe, North America, and Asia through sea freight, air freight, or express courier for urgent testing needs. Both FCL and LCL shipments are available.
Documentation Support
All necessary export documents can be provided for customs clearance, including commercial invoice, packing list, bill of lading or airway bill, certificate of origin, and food-contact compliance statements or test reports when applicable.
Sample Delivery
Material samples and short test tubes can be supplied for validation and equipment trials. Samples can be sent via DHL, FedEx, UPS, TNT, or using your appointed courier account.
After-Arrival Support
If any damage or discrepancies are discovered during unloading or inspection, customers may contact us within 7 days with photos and batch information. Our team will respond promptly to assess the situation and provide a reasonable solution.
