Start further away from the tube and move closer gradually.
Heat shrink tubing wire size chart.
Heat shrink frequently asked questions.
Size selection fluorotherm recommends size selection of an as supplied or expanded id sufficient to slip over the object to be covered so as to have the after shrinkage id smaller than the smallest dimension of the part.
Wrap around heat shrink tubing protect wire and cable without disconnecting them from an assembly.
For 16 gauge wire 3mm heat shrink tubing with a 2 1 shrink ratio and a 118 inch diameter is recommended.
Pick the right diameter.

3mm with a 2 1 shrink.
The wall thickness is also a consideration when choosing shrink tubing.
While a heat gun is the proper way to shrink the tubing if you don t mind scuffing up your soldering iron the barrel can be held close by to slowly shrink the tubing too about wire sizes.
The recommended heat shrink tubing size for 14 gauge wire is the same as that for 12 5mm with a 198 inch diameter.
Shrink tubing comes in an endless array of diameters but the diameter size is meaningless without knowing the shrink ratio.
Generally the tubing should be cut 4 to 10 longer than the overall length of the object as axial longitudinal shrinkage occurs.
Heat shrinkable tubing is primarily available in 2 1 or 3 1 shrink ratios meaning the tubing has been expanded to twice or three times its fully recovered size.
The greater the size variations of the underlying materials being covered the larger the shrink ratio required.
A different shrink ratio on each end allows this tubing to fit over cable assemblies and wire harnesses with large connections or around connectors with a 90 elbow.
Below are tables listing awg gauge wire sizes in addition to the thickness of common insulated.
The shrink ratio will define what size wire the tube will fit on.
This has a 2 1 shrink ratio at about 90 125 degrees c.
The recommended heat shrink tubing size for 18 gauge wire is the same as that for 16 gauge wire.
