護管端の止水栓。[Claims for Utility Model Registration] A water-swellable fiber composition mat that can be layered in the thickness direction is formed of a high water-swellable rubber composition and a low water-swellable rubber composition. The water-swellable fiber composition mat disposed on the outer peripheral surface and capable of being layered in the thickness direction is a nonwoven sheet of a mixture of 95 to 10 parts by weight of water-swellable fibers and 5 to 90 parts by weight of non-swellable fibers. The highly water-swellable rubber composition consists of 100 parts by weight of natural rubber or synthetic rubber composition and 30 parts by weight of water-absorbing resin powder.
~250 parts by weight of a mixture is vulcanized, and the low water swelling rubber composition contains 100 parts by weight of natural rubber or synthetic rubber composition and 0~250 parts by weight of water-absorbing resin powder.
A water stop valve at the end of a cable protection tube in which a cable is housed, which is made by vulcanizing a mixture of 30 parts by weight, and has a halved cut part in the radial direction of the cylindrical body.
