Often times it is difficult to create a waterproof electrical connection that will survive underwater. Traditional methods include potting, which takes a long time to set, or using underwater connectors, which can be expensive. Through much lab and field testing we have found that connections can be done in a short amount of time and in a cheap way using adhesive lined heat shrink.
We are selling packs of 5x 6in pieces. This brings the total length to 30 in [76 cm], enough to complete an entire OpenROV which has 21 external solder joints. We have added it as a replacement part as well as an experimental product for people who need to to attach their own components, hack the design, or are designing custom ROVs.
