PTFE tubing provides exceptional performance for applications requiring temperatures up to 260°C (500°F). Its superior thermal stability resists melt-off during soldering operations, while excellent dielectric properties make it ideal for electronics and electrical applications. The non-stick surface characteristics enable fluid transport with minimal resistance.
Chemical Compatibility
PTFE offers outstanding chemical resistance to virtually all industrial solvents, chemicals, and corrosive materials. Notable exceptions include fluorine, molten sodium hydroxide, and molten alkali metals.
Performance Advantages
Our extruded PTFE tubing outperforms glass and graphite alternatives through superior chemical resistivity and low coefficient of friction, making it optimal for critical fluid transfer applications. The material maintains dimensional stability under elevated temperature processing and can be steam sterilized without affecting physical properties including surface hardness, elongation, flex life, or deformation under load.
Available Configurations
Standard tubing appears translucent white (degree of opacity varies with wall thickness and manufacturing lot). Colored tubing is available to simplify system routing and identification during installation. Custom designs available upon request.

* This tubing has a safety factor of 5 to 1 (ratio of burst pressure to working pressure). This data is to be used as a guideline only. You should perform actual tests according to your specific application.
+ The following equation is for calculating burst pressure. The result from this equation is to be used as a guideline only. The calculation is at ambient room temperature. It does not factor steam pressure, altitude, etc.
B=Burst Pressure
T=Tensile Strength Values: FEP-3000 psi PFA - 4000 psi PTFE - 2500 psi PVDF - 5000 psi ETFE - 6500 psi
