GORE® STA-PURE® Pump Tubing, Series PFL
Avert tubing failure due to aggressive chemicals with this composite tubing structure that withstands clean-in-place (CIP) / steam-in-place (SIP) and enables consistent flow throughout processing.
Durable Tubing for Reliable Performance in Aggressive Chemical Applications
Challenging pharmaceutical and biopharmaceutical processes demand high performance solutions — including durable peristaltic pump tubing that reliably withstands aggressive chemicals and protects against catastrophic failure.
Silicone pump tubing has limited resistance to chemicals like organic solvents. But the patented composite of GORE STA-PURE Pump Tubing, Series PFL is engineered to resist aggressive chemicals including organic solvents. Series PFL tubing also delivers consistent flow rates at pressures up to 60 psig and is designed to work seamlessly in your existing processes.
Series PFL
Chemically Inert
- Provides better chemical compatibility than silicone or thermoplastic elastomer (TPE) tubing
- Performs reliably with common organic solvents
- Minimizes incidence of premature rupture
Compatible with CIP/SIP and Autoclave Sterilization
- Provides a flexible solution for industry-standard cleaning/sterilization procedures
- Supports sterile fluid processing
Available in Standard Sizes
- Retrofits easily to industry-standard peristaltic pumps. See a complete list of all our standard dimensions.
High Resilience
- Maintains process stability
- Delivers consistent flow rate
Aggressive Chemical Resistance
Series PFL was tested for durability to ensure reliable performance with aggressive chemicals as compared to deionized (DI) water. Twelve (12) samples were tested in a Watson-Marlow 600 Series two-roller peristaltic pump at a discharge pressure of 10 psig and speed of 165 rpm. The samples had a nominal ID of 12.7 mm and nominal WT of 3.2 mm. The samples were subjected to CIP/SIP conditions for 5 cycles (3 before and 2 during testing). Working fluids consisted of DI water (6 samples), and 99% concentrations of acetic acid, acetone, and ethanol (2 samples each). The mean tube life of the samples that underwent pumping of organic solvents was not significantly different from the samples that underwent pumping of DI water.
Technical Specifications
Unlike silicone tubing, Series PFL is manufactured with a patented composite of platinum-cured perfluoroelastomer and expanded polytetrafluoroethylene (ePTFE) for increased reliability with aggressive chemicals in peristaltic pumps.

a Continuous pumping of room temperature deionized water in Watson-Marlow 500 and 600 Series peristaltic pumps. The 500 Series pumps were used for testing at 60 psig with pump head speed of 220 rpm (two rollers). The 600 Series pumps were used for testing at 10 psig with pump head speed of 165 rpm (two rollers). Samples selected represent the worst-case configuration of pump and tube size based on mechanical stresses imposed by the pump on the tube.
b Tube size = 12.7 mm (ID) x 3.2 mm (WT); When testing was terminated at a minimum of 330 hours, all 6 samples were performing without failure. Failure is defined as rupture, leakage, sustained flow reduction of 25 percent or more, or inability to sustain operating pressure. Tubing was subjected to conditions similar to 5 CIP/SIP cycles (3 before and 2 during testing).
c Tube size = 6.4 mm (ID) x 2.4 mm (WT); 6 samples were tested until failure as defined in (b) above. The operating life until failure is presented as the average and standard deviation for all samples. The minimum observed value was 28 hours. Before testing, tubing was subjected to conditions similar to 1 CIP/SIP cycle.
