Tygon S3 Long Flex Life Pump Tubing #E-LFL (Formerly "Long-Flex-Life Pump Tubing")

Tygon S3 Long Flex Life Pump Tubing #E-LFL (Formerly "Long-Flex-Life Pump Tubing")

Tygon S3™ Long Flex Life Tubing offers the longest peristaltic pump life of any clear Tygon® tubing formulation.


Crystal-clear Tygon S3™ E-LFL tubing is formulated specifically for use in peristaltic pump applications. The new Tygon S3™ E-LFL non-DEHP tubing has even longer pump life not only at 0 psi but also at back pressure of up to 25 psi. With its superior flex life characteristics, Tygon S3™ E-LFL tubing reduces production downtime due to pump tubing failure. Our tests demonstrated reduced particle spallation, which eliminates the need for frequent downstream filter replacement and diminishes the risk of sensitive-fluid contamination.

The non-aging and broad chemical resistance properties of Tygon S3™ E-LFL enable users to utilize the new tubing for transferring chemicals, cleaning agents and bactericides without danger of corrosion (as with metals) or oxidation (as with rubber). Tygon S3™ E-LFL is safe and non-toxic and can be sterilized through conventional autoclave methods (steam 30 minutes at 15 psi, 121°C) and Ethylene Oxide, making it an excellent choice for high purity applications. It can be produced in up to a 2" (5.08 cm) inside diameter, ideal for bulk transfer applications.
