Key Advantages
Outstanding Chemical Resistance
Santoprene pump tubing provides excellent resistance to acids, alkalis, alcohols, oils, lubricants, and many aqueous solutions. It handles aggressive chemicals better than many silicone or PVC alternatives in non-hydrocarbon applications.
Common compatible media include alcohols, dilute acids/bases, and water-based fluids. Always verify specific chemical compatibility for your application.
01
Superior Flexibility & Fatigue Life
Designed for repeated compression in peristaltic pumps, Santoprene tubing offers outstanding flex fatigue resistance and resilience. It often delivers significantly longer pump life (higher cycle counts) than standard silicone tubing, reducing downtime and replacement costs.
Its elastic recovery maintains consistent flow rates over extended operation.
02
Wide Temperature Range
Santoprene tubing performs reliably from -60°C to +135°C (-76°F to +275°F), supporting both hot and cold fluid transfer as well as sterilization processes.
03
FDA / USP Class VI Compliance
Medical and food-grade versions meet FDA 21 CFR, USP Class VI, NSF, and RoHS standards. It is phthalate-free, latex-free, and suitable for high-purity applications.
04
Material Science
Santoprene is a thermoplastic vulcanizate (TPV) created through dynamic vulcanization of EPDM rubber in a PP matrix. This gives it the strength and chemical resistance of vulcanized rubber combined with easy extrusion and recyclability of thermoplastics.
Comparison Highlights:
Vs. Silicone: Better chemical resistance to certain solvents/acids; often longer peristaltic life; lower cost in many cases.
Vs. PVC: No plasticizers (no leaching); better temperature range and elasticity.
Vs. Tygon/Viton: More flexible and cost-effective for many general fluid transfer needs.
Available Hardness: Common options include 40A, 50A, 64A, and 73A Shore A. Harder grades (e.g., 64A) often optimize occlusion and longevity in peristaltic pumps.
It contains no halogens or added plasticizers, making it environmentally friendlier and safer for sensitive fluids.
Applications
Medical & Pharmaceutical
Santoprene tubing medical grade is ideal for peristaltic pumps in drug delivery, bioprocessing, dialysis, and fluid management. USP Class VI compliance ensures biocompatibility for GMP production lines and sterile applications.
Laboratory & Life Science
Peristaltic pump tubing lab applications benefit from precise flow control, chemical resistance, and easy sterilization in analytical instruments, cell culture, and research equipment.
Food & Beverage
Food grade Santoprene tubing handles dairy, beer lines, syrups, beverages, and hot/cold food processing. FDA and NSF compliant, it resists oils and maintains taste/odor neutrality.
Chemical Processing
Chemical resistant pump tubing transfers acids, alkalis, and cleaning solutions reliably in industrial settings.
Water Treatment
Durable flexible tubing for water, wastewater, and treatment chemicals with excellent abrasion and fatigue resistance.

FAQ
Q: What is Santoprene pump tubing used for?
A: It is used in peristaltic and metering pumps for reliable fluid transfer in medical, food, chemical, and lab applications.
Q: How long does Santoprene tubing last in a peristaltic pump?
A: It typically offers superior flex life compared to silicone, often lasting significantly longer under continuous operation due to excellent fatigue resistance.
Q: Is Santoprene tubing FDA approved?
A: Yes, food and medical grades meet FDA 21 CFR and USP Class VI standards.
Q: What is the difference between Santoprene and silicone tubing?
A: Santoprene generally provides better chemical resistance to acids/alkalis, comparable or longer pump life, and no plasticizer leaching, while silicone excels in very high-temperature inertness.
Q: Can Santoprene tubing handle aggressive chemicals?
A: Yes, it resists a wide range of acids, bases, alcohols, and aqueous chemicals. Consult a compatibility chart for specifics.
Q: What sizes are available for Santoprene pump tubing?
A: Standard and custom sizes from 0.5 mm ID upward, with various wall thicknesses.
What temperature can Santoprene tubing withstand? Continuous service from -60°C to +135°C.
Q: Is Santoprene tubing suitable for food and beverage applications?
