PTFE Flexible Tubing

PTFE Flexible Tubing (Virgin PTFE, Extruded & Braided Options)

Kaxite PTFE flexible tubing is extruded from 100% virgin PTFE resin and supplied as a chemically inert, heat-resistant, low-friction flexible tube. It resists crimping and kinking better than rigid PTFE tube, works continuously from −200 °C to +260 °C (short-term peaks up to +300 °C), and is the preferred choice for chemical transfer, electrical insulation, pneumatic lines, laboratory and food-grade fluid handling. Standard bore: 3 mm to 28 mm, wall thickness 0.7 mm to 2 mm. Custom bore, wall, coil length and SS overbraid are available for OEM and bulk orders.

As a direct PTFE flexible tubing manufacturer in Ningbo, China, Kaxite supplies both off-the-shelf coils and custom-extruded runs. Buyers looking for a reliable PTFE tubing supplier use this page to check sizes, temperature and pressure performance, and to request a bulk quotation. If you need rigid profiles instead, see our PTFE Tube, PTFE Pipe and PTFE Hoses pages.

Types & Construction Options

Standard

Virgin PTFE Flexible Tubing

• 100% virgin PTFE, extruded to a concentric, smooth-bore flexible tube.
• Chemical inert, low friction, non-stick and non-toxic — suitable for food and pharmaceutical contact.
• Best electrical insulation of any flexible plastic tubing.

High Pressure

SS Overbraided PTFE Flexible Tubing

• SS 304 / 316 stainless steel braid over the PTFE core for higher burst pressure.
• Used in hydraulic, chemical transfer and steam lines that need flexibility plus pressure resistance.
• Available with or without end fittings — please provide a drawing.

Prime Features

• Wider temperature range: works up to +260 °C continuously, with a short-term peak of +300 °C; remains flexible at cryogenic temperatures down to −200 °C.
• Superior electrical performance: very high concentricity, a critical parameter for insulation and dielectric applications.
• Burst pressure: lower wall thickness can be selected for cost saving when pressure demands allow; SS overbraid available for high-pressure lines.
• Abrasion resistance and flex: long flex life reduces downtime and replacement cost in vibrating or moving equipment.
• Smooth internals: perfectly smooth bore allows easy insertion of members and low flow resistance, thanks to the low coefficient of friction of PTFE.
• Chemical resistance: inert to almost all acids, bases and solvents — a reliable barrier in aggressive media.
• Non-toxic and chemically inert: suitable for food, beverage and pharmaceutical contact applications.

Technical Data

Packaging & Delivery

PTFE flexible tubing is coiled or cut to length, protected with interleaving film, and packed in cartons or on pallets to prevent kinking and surface marking during shipping. Custom carton marking, coil labelling and private-label packaging are available for OEM and bulk orders.

• Standard coils and cut-to-length tubes protected with interleaving film and packed in cartons or on pallets.
• SS overbraided tubing coiled with protective end caps to protect the braid and bore.
• Custom carton marking, pallet labelling and private-label packaging available.
