After crimping the butt connector it must be shrunk using a heat gun.

The butt connector has an internal layer of glue which is released when heated and flows out and around the cables. The glue and crimp together provide a mechanically robust and moisture proof splice.

Use a heat gun with a high enough rating to shrink the crimped butt connector.

Inspect results of shrinking

Check the shrinking results. If ok the glue should have been forced out of the ends of the butt connector and around the splice.
