A very useful derivative of insulating tape which can be used for waterproofing connections. To use, the top protective layer is peeled off and the rubbery self- amalgamating tape underneath is wrapped tightly around the connection to be waterproofed. Eventually, the layers of this tape will merge together and create a waterproof seal. This tape is highly recommended for automotive work and also aerial installations, particularly those for satellite TV where cables enter the LNB and polariser. The tape is black, 19mm wide and is supplied on 5m reels.
