We understand every medical device assembly is unique. Just send us your drawings, samples or initial technical ideas, and our engineering team will work through key parameters like ID, OD, wall thickness and length. We don't only supply tubing - we tailor the right solution to fit your assembly perfectly.
Product Features
PTFE SheathTubing Key Advantages
We are looking for a cooperative partner to expand our business.
Low-friction smooth surface
PTFE has an inherently low coefficient of friction, greatly cutting sliding resistance during device operation. It delivers smooth movement for precise interventional procedures and complex lumens, improving clinical feel and response.
Outstanding chemical resistance
Our PTFE sheaths stand up well to most cleaners, disinfectants and various chemical media. Our technical team can assess material compatibility for your application to keep performance stable throughout use.
Wide range of sizes for flexible fitting
We keep standard sizes in stock for fast lead times. We also offer custom ID, OD, wall thickness and length, so the sheath fits your limited or unique assembly space perfectly.
Full custom support from design to finished part
Share your drawings, samples or basic ideas with us. Our engineering team works with you to confirm critical dimensions, tight tolerances and inspection requirements before production, matching your design intent.
Dual service for standard and custom orders
Project timelines vary. We supply ready standard parts for fast delivery, and offer dedicated custom support for special, high-tolerance new designs. We find the best solution for every requirement.
Special processing for better control and visibility
We apply special treatment to boost tube stiffness and clarity. Stiffer tubing offers good pushability for accurate navigation inside complex anatomy. Higher clarity improves visual feedback, helping your medical device perform better clinically.
Applications
Stone Retrieval Basket Instruments
Our PTFE sheath tubing comes with a low friction coefficient. It effectively reduces sliding resistance between stone retrieval basket parts, enabling smooth opening and retraction of the basket and bringing a comfortable handling experience for operators.
Precision Device Components
For compact internal structures of precision medical devices, we supply custom-sized PTFE sheath tubing with tight dimensional control. We strictly manage tube diameter and wall thickness to deliver reliable protection and ideal fit for your assemblies.
Endoscopic Polypectomy Snare
Our PTFE sheath tubing provides reliable coverage for the inner wire of endoscopic polypectomy snares. The tubing offers insulation and a precise fit, allowing the snare to advance safely through narrow lumens.
Technical Parameters
Inner diameter range:
0.15 and above
Tolerance:
± 0.02 mm- 0.05 mm
Wall Thickness:
0.025mm and above
FAQ
Q: What is Custom Medical PTFE Sheath Tubing?
A: Simply put, it is a custom-fitted polytetrafluoroethylene sheath tubing built exclusively for medical device assemblies. Whether you need readily available standard sizes or special custom specifications for unique designs, we can develop the best tubing solution based on your drawings and real application conditions.
Q: Do you carry standard PTFE sheath tubing?
A: Yes, we do. We keep a wide range of standard sizes in stock. If these fit your design, off-the-shelf options help you save lead time and cost. We also offer dedicated custom manufacturing if you have special requirements for ID, OD, wall thickness or length.
Q: Can you produce thin-wall PTFE sheath tubing?
A: Yes we can. That said, the thin-wall limit depends on the ratio between inner and outer diameter plus your tolerance requirements. To work out a feasible solution, please share your drawing or dimension specs. Our engineers will review the production process promptly and give you a clear answer.
Q: What information do you need for quoting custom PTFE sheath tubing?
A: To calculate an accurate, competitive price quickly, please prepare the details below where possible:
- Key dimensions: ID, OD, wall thickness and length
- Dimensional tolerance requirements
- Material grade and other technical specifications
- Product drawing or physical sample (if available)
- Estimated order quantity
- Working environment or special requirements The more details you provide, the more precise our quotation and solution will be.
Q: Is PTFE sheath tubing compatible with sterilization?
A: PTFE itself offers excellent resistance to sterilization. Still, suitability for your specific sterilization method (autoclave, EO, etc.) depends on wall thickness, sterilization temperature and cycle counts. Kindly tell us your sterilization process when you send an inquiry. We will confirm material suitability and support your validation tests.
Q: Can you offer cleanroom manufacturing and relevant quality documents?
A: Absolutely. We fully understand strict compliance requirements for medical projects. If you require cleanroom production, Certificate of Conformance (COC), inspection reports or quality system documents, just mention these needs in your inquiry. We will arrange proper production conditions and prepare the full set of quality records for you.
