Moled Teflon Hollow Tube Rod
Product Details
Our molded PTFE hollow tube rods are designed for demanding industrial environments where corrosion resistance, dimensional stability, and reliable performance are essential. Produced using high-purity PTFE material, these rods offer excellent resistance to aggressive chemicals and extreme temperatures ranging from -200°C to +260°C.
The hollow construction reduces weight and material costs while providing sufficient strength for machining into custom components. The rods are easy to machine using CNC equipment and are widely used in chemical processing, semiconductor manufacturing, electrical insulation, food processing, medical equipment, and fluid handling systems.
Available in standard sizes or custom dimensions, our molded PTFE hollow rods can be supplied in natural white or customized colors according to project requirements.
Material
Manufactured from 100% virgin PTFE (Polytetrafluoroethylene) resin, our molded hollow rods deliver consistent quality and long service life. PTFE is well known for its exceptional resistance to nearly all chemicals, excellent dielectric properties, and one of the lowest coefficients of friction among engineering plastics. It does not absorb moisture, resists UV exposure and weathering, and maintains stable performance under continuous high temperatures. Virgin PTFE also meets FDA compliance for many food-contact applications and can be supplied with material certifications upon request.

FAQs
Q1. What is the difference between molded PTFE hollow rods and extruded PTFE tubes?
Molded PTFE hollow rods are manufactured by compression molding, making them suitable for larger diameters and thicker walls with excellent dimensional stability. Extruded PTFE tubes are better suited for small diameters and continuous production.
Q2. Can you manufacture custom dimensions?
Yes. We produce custom outer diameters, inner diameters, lengths, and wall thicknesses according to customer drawings or specifications.
Q3. Is virgin PTFE better than filled PTFE?
Virgin PTFE offers the best chemical resistance, purity, and electrical insulation. Filled PTFE grades, such as glass fiber, carbon, bronze, or graphite filled PTFE, provide improved wear resistance and mechanical strength for specific applications.
Q4. Can the hollow PTFE rods be CNC machined?
Absolutely. Our molded PTFE hollow rods are widely used for CNC machining into bushings, seals, valve seats, spacers, rollers, and other precision components.
Q5. What information should I provide for a quotation?
