Kaxite Sealing manufactures PTFE flexible tubing from 100% virgin PTFE resin by paste extrusion, producing semi-flexible tubing in ID 1–28 mm and wall 0.5–2.5 mm. Chemically inert across pH 0–14, service range -200 to +260 °C, dielectric strength above 400 kV/cm and self-lubricating with the lowest coefficient of friction of any solid material. Supplied in straight lengths, coils or cut pieces, with FDA and USP Class VI grades, anti-static options and SS 304 / 316 overbraid available. Procurement teams choose us for factory-direct bulk pricing, documented traceability and 7–15 day lead times.
Four reasons procurement teams in chemical, pharmaceutical and semiconductor industries specify Kaxite as their PTFE tubing supplier.
Buy straight from the extruder. No trading markup, no hidden broker fees — landed cost reductions of 15–30% compared with reseller channels. MOQ from 50 m per size.
Every batch ships with a material certificate of analysis, FDA / USP Class VI declaration and dimensional inspection report. Full audit trail from resin lot to delivery.
Standard sizes ship in 7–15 days. Custom bore, cut-length and overbraided variants ship in 15–25 days. Emergency stock is available for repeat customers.
Custom colours, laser marking, flared ends, skived tubing and SS 304 / 316 overbraid. Send your drawing — engineering feedback within 24 hours.
Semi-flexible tubing extruded from 100% virgin PTFE resin. Available in five engineered grades — standard transfer (STD), high-purity smooth bore (SM), conductive anti-static (CON), high-pressure wall (HP) and stainless-steel overbraided (BRAID) — to cover chemical transfer, pharmaceutical, semiconductor, food and high-vibration service.
Transfer of aggressive acids, alkalis, solvents and high-purity process fluids. Used in reactor feed lines, sampling lines and chromatography systems. Pairs with our PTFE pipe for large-bore trunk lines.
Sanitary transfer lines for flavours, colours and aggressive food products such as vinegar. Ideal for clean-in-place (CIP) and steam-in-place (SIP) systems with FDA 21 CFR compliance.
High-purity gas and chemical delivery for etch, deposition and cleaning processes where ultra-clean, outgassing-free performance is critical.
Autosamplers, peristaltic pumps and liners for corrosive gas sampling. Its inertness prevents sample contamination. See our PTFE tube range for rigid-bore alternatives.
Fluid lines for fuel, lubrication and hydraulic systems in high-temperature engine compartments, or for de-icing fluids.
High-temperature, chemically resistant insulation for wires and cables in harsh conditions. Pairs with our PTFE hoses in flexible connection points.
PTFE tubing offers far superior chemical resistance, a much broader operating temperature range (-200 to +260 °C), better non-stick properties and higher purity. While PVC or polyethylene may suit general-purpose water or air lines, PTFE is essential for aggressive chemicals, high temperatures or where contamination must be avoided.
Yes, our PTFE tubing handles intermittent steam exposure due to its high-temperature resistance. For continuous steam service, consult our technical team regarding pressure and temperature specifics, as long-term exposure at the upper end of the temperature range may affect the pressure rating.
PTFE is a relatively soft material. For a secure, leak-proof connection under pressure or vacuum, we recommend compression fittings designed for soft tubing or flared fittings. Barbed fittings can be used for low-pressure applications but should be secured with hose clamps.
Standard PTFE tubing is naturally opaque white. Kaxite Sealing offers specially formulated grades that are translucent, allowing visibility of fluid flow. Opaque versions provide excellent UV resistance for outdoor use.
PTFE tubing is semi-flexible. Flexibility depends on wall thickness and diameter. Smaller-diameter tubing with thinner walls bends to a relatively tight radius without kinking. Larger diameters with thicker walls require a larger minimum bend radius. Always follow the minimum bend radius guidelines in our technical datasheets.
Absolutely. We produce specific grades compliant with FDA Title 21 CFR for repeated food contact and meet USP Class VI standards for biocompatibility, manufactured under controlled conditions for food, beverage and pharmaceutical applications.
Cleaning is straightforward due to PTFE's non-stick surface. Most residues can be flushed out with appropriate solvents. Our tubing is fully autoclavable (typically up to 121 °C / 250 °F, 15 psi) and withstands gamma irradiation or ethylene oxide (EtO) sterilization.
PTFE is an extremely stable polymer with an essentially indefinite shelf life when stored properly. Keep it in a cool, dry place away from direct sunlight and sources of excessive heat. Store coiled loosely or laid straight to avoid permanent deformation.
Yes. Kaxite Sealing offers extensive custom fabrication services — flared tube ends, skived (split) tubing, printing and colour-coding for easy identification. We work with clients to develop tailored solutions for unique application challenges.
Send us your inner diameter, outer diameter, wall thickness, coil or straight length, grade preference or finished-part drawing. Our export team replies within 24 hours and confirms grade selection, lead time, packaging and documentation before you place a bulk order.
