Description: DAFLON SH421 Shrinkable PTFE Tubing recovers to approximately 25% of its expanded size when heated to the gel point (621°F). Thus it is now possible to use shrinkable PTFE tubing, with its excellent chemical and physical properties, over objects which require more than the standard 2:1 shrink down ratio.
Note: Tubing should be allowed to recover at least 50%.
Conforms to Mil-I-23053/12, Class 5, and AMS-3584.VW-1.
This series is RoHS compliant.
