*Only PVC tubing with a nominal OD of 5.5 mm (0.215 in) and a nominal wall thickness of .84 mm (0.033 in) has been tested by Terumo BCT for weld strength and sterility; however, some users have had successful results using other types of thermoplastic tubing (such as C-Flex). If you choose to use tubing other than the tubing specified, it is your responsibility to test for weld strength and sterility according to the standards appropriate for the desired application. Use of tubing other than the PVC tubing specified can cause a low-strength weld joint, which could result in a non-sterile weld.
