S4R PTFE Chemical-Resistant Tubing is designed for fluid transfer in laboratory, electrochemical and chemically demanding environments. PTFE combines broad chemical resistance, low surface friction and excellent thermal stability with very low moisture absorption and good electrical insulation properties. The tubing is supplied in a natural milky-white translucent finish and is available in selected metric sizes for laboratory, analytical and fluid-handling systems.

Key Features

✓ PTFE fluoropolymer construction

✓ Broad resistance to strong acids, alkalis and many chemical media

✓ Low-friction, non-stick surface characteristics

✓ Service temperature range from −190 to +260 °C*

✓ Very low water absorption and good electrical insulation

✓ Six metric sizes with 1 m, 5 m and 10 m length options

Typical Applications

• Laboratory chemical and reagent transfer

• Solvent and corrosive fluid handling

• Electrochemical and battery research equipment

• Analytical and scientific instrumentation

• Laboratory gas and liquid transfer lines

• Chemically demanding laboratory installations

Chemical & Installation Compatibility

PTFE provides broad chemical resistance, but actual compatibility and operating limits depend on the chemical medium, concentration, temperature, pressure, tubing dimensions, fittings and installation conditions. The −190 to +260 °C range is manufacturer-stated and should not be interpreted as a universal continuous operating range for every application. The 327 °C value represents the material melting point and is not a recommended service temperature. For pressurized, vacuum-critical or safety-critical systems, verify the complete installation under the intended operating conditions before use.
