A very useful derivative of insulating tape which can be used for waterproofing connections. To use the top protective layer is peeled off & the rubbery self- amalgamating tape underneath is wrapped tightly around the connection to be waterproofed. Eventually the layers of this tape will merge together & create a waterproof seal. This tape is highly recommended for automotive work & also aerial installations particularly those for satellite TV where cables enter the LNB & polariser. The tape is black 19mm wide & is supplied on 10m reels.
