Note
For a secure fit, it is necessary that the tubing's recovered diameter (the diameter after shrinkage) is smaller than the diameter of the area to be insulated. At the same time, the tubing's expanded diameter (the diameter before shrinkage) needs to be large enough to fit easily over the area to be insulated, as well as any connectors attached to it.
Approvals
UL, CSA, AMS-DTL-23053/5 Class 1
