There are hundreds (maybe thousands) of these types of products doing similar jobs. These splices (below) do work very well, have stood the test of time and are well respected in the aviation industry; however I am sure there are equally as good (or better) products around.
They are rated "immersion resistant" but be aware of the cable temp. requirements. Other pages on the link below show heat shrink solder terminations. These do work but I don't like them unless used by an EXCELLCENT operator. I have seen too many failures even when used by reasonably competent technicians.
Except in high vibration enviroments, I just prefer a GOOD soldered joint, smeared with some DC4 (silicon grease) and covered with heat shrink; quick, simple, cheap
and if done well - reliable.
