A tape wrapping and dispensing device for wrapping stretchable tape around a pipe. The device has at least three tension rollers that are mounted at the dispensing end of a support plate, the tension rollers defining a first nip between an upper and intermediate roller and a second nip between the intermediate roller and a lower dispensing roller. In use, a free end of the stretchable tape can be removed from the supply roll and passed, first, between the first nip and then between the second nip before being secured to a pipe or other elongate body, and then, with the lower dispensing roller in direct contact with the stretchable tape secured to the pipe or other elongate body, the device can be moved in a first circumferential direction around the pipe to cause rotation of the lower dispensing roller and simultaneously dispense and wind the tape therearound.

Fluid leak repair kits are described comprising a putty, self-amalgamating tape, and a composite material for use in encompassing the self-amalgamating tape. The composite material comprises a flexible sheet or tape and a matrix component for binding the flexible sheet or tape. The matrix component comprises a resin or water-activated matrix component which, when cured, forms an outer shell.
