Pros

  • Crimp, Heat and Forget

Comments about Heat Shrink Butt Connectors:

These are great to use anywhere but the heat shrink material is easy to nick when crimping wire. I also then coat with liquid electric tape to completely seal.

      Comments about Heat Shrink Butt Connectors:

      Pulled my boat out of storage and got it ready for the year. As I began testing my electrical systems, nothing worked. I troubleshot each individual system to the helm switches and knew they all needed to be replaced. I took my time replacing them all and replaced each non-marine connection with new marine butt connectors for the specific applications.

        Comments about Heat Shrink Butt Connectors:

        Salt air is your worst enemy for ground wires in boats. It's so much easier to use the right stuff to begin with. It will prolong the time before you have to do it again. Because you will have to do it again anyway.

              needed the product to quickly fix Live Well Pump at the last minute. they quickly creams on and with little heat they sealed up nice and dry. I'm very pleased with this product

              All or nothing

                    Comments about Heat Shrink Butt Connectors:

                    With waterproofing, it's really an "all or nothing" scenario. It's dry or it's wet. They worked for me. The only caution is that that the connection wire must be clipped a bit short my comfort so I also used the shrink tube as a precaution.

                      I have used other brands, and found that they did not seal as advertised. These Ancor connectors work very well - and seal evenly every time. They also don't seem to require as much heat as some others.

                          Comments about Ancor Marine Heat Shrink Butt Connector, 22-18 Wire Gauge, Red, 25 Qty/pkg:

                          These things do not shrink down to fit snugly even when a lot of heat is applied, thus are not water-tight and not weather resistant. The regular heat-shrink tubing works much better in my opinion, and it's quite a bit cheaper.

                              We use this in Automatic carwashes. It survives in freezing, mucky, wet, abusive conditions. Even at nearly a buck each, they are worth it!
