flexible ptfe tubing

PTFE Flexible Extruded Convoluted Tubing OEM Manufacturer

PTFE Tubing Flexible Product Description：

1. Polytetrafluoroethylene (PTFE) convoluted tube is made of modified standard PTFE. Compared with most fluoropolymers, it has excellent bending life performance and greatly improves the resistance to stress cracking.

2. Compared with standard materials, the PTFE spiral tube has fewer pinholes and lower penetration, which makes it an excellent choice for the transmission of fine chemicals and highly searchable gases (such as chlorine) .

3. PTFE can be made into corrugated PTFE pipe, which has excellent flexibility. Anti-static design (black) or straight end (for connectors/accessories) are also available. In addition to PTFE, we also provide PFA, FEP and PVDF bellows.

We can also provide stainless steel braided corrugated PTFE tube, whose engineering strength will be greatly increased

Key properties of convoluted PTFE tubing:

• UV-resistant (does not age)

• Almost absolutely chemical inert

• FDA- approved (suitable for food industry)

• Applications from -50 up to 260°C

• No attachment (easily to clean)

• Vacuum lasting up to 90%

• Electric isolated (high dielectricity)

Factory-PTFE-Teflon-100-Virgin-Extruded-Smooth-Flexible-Tube-Hose — PTFE Customized Flexible Extruded Smooth Bore Tubing OEM Manufacturer

**Ptfe Flexible Tubing Product Description：**

1. Polytetrafluoroethylene was first discovered in the 1930s by Dr. Roy Plunkett, a scientist at DuPont, and was first used in the top-secret Manhattan Project during World War II.

2. In the late 1940s, DuPont commercialized polytetrafluoroethylene (PTFE) under the name of PTFE. Extrudable grades of PTFE were later commercialized.

3 .As the polymer of choice for many advanced applications, polytetrafluoroethylene has many unique properties. Polytetrafluoroethylene has the lowest coefficient of friction of all polymers and a very wide operating temperature range, so it can be applied to various products from advanced medical equipment to high-temperature industrial equipment. Due to its incomparable chemical inertness, PTFE has become the plastic of choice in the chemical and analytical science industries.

4 .Our PTFE plastic can be made into various sizes of PTFE pipes (and modified PTFE). Smooth or curved (spiral or parallel), metric, imperial and AWG sizes. PTFE pipes can be made into straight pipes and packaged in coils or spools, and the cutting length can be customized. The natural color of PTFE tubing is milky white until slightly transparent. Other colors and pads are also available (in stock).

**FAQ**

Q: Are you a manufacturer?

A: Yes, we have our own R&D department and more than 50 production lines, and we provide OEM and ODM service.

Q: Do you offer free samples?
A: Yes, we provide free samples for testing. The quantity depends on specifications, but shipping costs may apply (or be paid upon delivery). Contact our sales team for sample availability.

Q: What is the delivery time?
A: We have most of sizes in stock and can them immediately, standard orders are delivered within 3-5 working days (from order confirmation). Custom sizes or bulk orders may require longer lead times, which we will communicate in advance.

Q: What material options are available?
A: We offer multiple PTFE material choices, including:
• Domestic high-quality brands: Such as Dongyue, cost-effective and compliant with local standards.
• International brands: Such as Daikin and Chemours, known for superior performance in demanding applications.
We can recommend the best material based on your needs.

Q: Do you assist with import customs clearance? What documents are provided?
A: Yes, we provide full customs clearance support, including:

Certificate of Origin (C/O)
• Certificate of Analysis (COA)
• Material Safety Data Sheet (MSDS)
• Commercial invoice & packing list
• Customs declaration (if required)
Additional documents can be arranged upon request.

Q: What are the temperature and chemical resistance properties?
A: PTFE tubes can operate in -200°C to +260°C and resist strong acids, alkalis, and organic solvents (e.g., sulfuric acid,
hydrofluoric acid), making them ideal for chemical, semiconductor, and harsh environments.

Q: Can you customize sizes and colors?
A: Yes! We customize inner/outer diameters, wall thickness, and length. Standard color is white; other colors (e.g., black,
transparent) require a minimum order quantity (MOQ).

Q: How do you ensure product quality?
A: We guarantee quality through:
• Traceable raw materials.
• Pre-shipment inspections (dimensions, pressure tests, etc.).
• Third-party test reports (e.g., SGS) upon request.

Q: What payment methods are accepted?
A: We accept T/T (Bank Transfer), L/C (Letter of Credit), Alipay/WeChat Pay (for small orders) and other terms.

Terms are confirmed in the contract.

Q: What if there are issues after delivery?
A: For quality concerns, please keep the original packaging and provide photos/videos. We will respond within 24 hours to
arrange returns, replacements, or compensation.
