Black filling mastic GZZ-4

    Black tapes are applied to the cable connection in a stretched form (up to 30%) overlapping each other. As a result, the layers of the tape stick together, forming a homogeneous mass similar to the cold vulcanization technology. It is used when sealing the "coupling neck" - protects against moisture penetration at the point of cutting the armor on the cable sheath in cable couplings. It is used in couplings at the points of connection of the grounding wire in cable couplings. The set includes 4 sealant tapes.
