Heat activated adhesive inside the heat shrink tubing seals the wires from any harsh environment. These crimp connectors will protect your wiring against strain and vibration. Unlike their vinyl and nylon counterparts, these wire crimp connectors are able to stand up to the harsh marine and automotive environments.
Heat Shrink Butt Connectors
Very happy with purchase. Just wish you could buy quantity of ring terminals only.
Good price, good quality for heat shrink connectors.
These really do keep the connection waterproof. That was what I was expecting to get and that is what I got.
These seal extremely well, will order again.
