Tubing, Thermoplastic Tubing

Tygon S3™ E-LFL

Tygon S3™ E-LFL is a clear, flexible tubing developed for peristaltic pump-driven fluid delivery in medical devices, with a particular strength in high-pressure applications such as cardiac irrigation and surgical pump systems. Capable of maintaining flow integrity at back pressures up to 25 psi, E-LFL is ideal for systems that require precise, consistent fluid control under dynamic conditions. Formulated with bio-based, DEHP-free plasticizers, Tygon S3 E-LFL meets USP Class VI, NSF-51, and EU 10/2011 compliance requirements, making it well-suited for use in patient-contact devices and fluid pathways requiring high material consistency. Its clarity supports visual flow verification, while its low gas permeability compared to silicone helps protect fluid composition over time.
