PFA tubing represents the premium fluoropolymer solution, combining the chemical inertness of PTFE with enhanced mechanical properties and processing advantages. Engineered for the most demanding applications, PFA delivers exceptional crack and stress resistance while maintaining superior performance at elevated temperatures up to 260°C (500°F).
Performance Characteristics
• Superior thermal stability exceeding FEP capabilities
• Enhanced flexibility and long flex-life under thermal cycling
• Lower permeability than FEP for improved containment
• Translucent construction enabling visual flow monitoring
• Non-flammable with exceptional chemical resistance
• Near-zero moisture absorption for dimensional stability
• Maintains mechanical strength at maximum service temperatures
High Purity Grade
PFA HP (High Purity) tubing offers ultra-low chemical extractables for semiconductor and pharmaceutical fluid handling applications where contamination control is critical.
Available Configurations
Standard and custom diameters available in straight lengths, coiled hose constructions, and convoluted designs. Compatible with flare and conventional fittings for versatile system integration. FDA compliant for food contact applications.
Applications
PFA tubing serves the most demanding applications in semiconductor processing, pharmaceutical manufacturing, chemical processing, and high-temperature fluid transfer systems where the combination of extreme chemical resistance, thermal stability, and mechanical durability is essential.
Key Advantages
PFA uniquely combines PTFE’s chemical inertness with FEP’s clarity and processing benefits, while delivering superior mechanical properties and higher temperature capability, making it the optimal choice for critical high-performance applications.

* 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
1 bar = 14.504 ps
