Fluoropolymer tubing does not have a determined shelf life.
Heat Shrink Shelf / Dimensional Life
PTFE and FEP heat shrink tubing conforming to AS23053 have a minimum dimensional life of four years when stored at their specified temperatures. This feature means that these heat shrinks can be used as long as they’re expanded inside diameter (ID) and recovered wall ID remain within the tolerances specified in AS23053/11 and AS23053/12.
Etched fluoropolymers will “grab” or capture molecules from the air to restore their electron deficiency. This process results in a weakening of their surface etching. For this reason, all etched materials should be stored in their original sealed bags. Zeus ships all etched tubing orders in sealed black protective bags.
