C-Flex 374 Tubing

C-Flex® is the original patented thermoplastic elastomer tubing specifically designed to meet the critical demands of pharmaceutical and biopharmaceutical applications for fluid processing with excellent heat seal and sterile weld capabilities.

For over 25 years, C-Flex has been the thermoplastic elastomer tubing most widely used and validated by the world's leading pharmaceutical and biopharmaceutical companies. Each coil of C-Flex tubing is extruded to precise ID and wall dimensions. All tubing is formulated to meet the standards of the biopharmaceutical industry and is quality tested before leaving the Saint-Gobain Performance Plastics production facilities.

C-Flex tubing is part of a family of TPE tubing offering the widest range of formulations and sizes in the industry including translucent tubing for fluid flow visibility, opaque tubing for application when sensitivity for light is required and custom formulations from 50A to 80A durometer. C-Flex is also available as C-Flex Braided to use in applications where a thermoplastic tube is desired, but the pressure requirements exceed those allowable by a non-reinforced thermoplastic material. All are available in custom sizes, lengths and packaging. C-Flex tubing has a secure global supply chain with redundant manufacturing sites in the United States and Europe with validated manufacturing processes.

C-Flex tubing is manufactured from pharmaceutical-grade thermoplastic materials and is fully characterized, validated and tested to a variety of specifications including USP Class VI, ISO 10993-3 (Ames Genotoxicity), ISO 10993-4 (Hemolysis, Indirect), ISO 10993-5 (Cytotoxicity, In-Vitro), ISO 10993-11 (Systemic Toxicity, In-Vivo) and European Pharmacopeia. Extensive biological, chemical, physical properties and extractable testing performed on unsterilized and sterilized C-Flex tubing is available to assist in the validation of C-Flex application.
