FIELD: transportation.
SUBSTANCE: invention can be used for storage, transportation and distribution of compressed gases to consumers. High-pressure gas cylinder includes housing from composite material lined inside sealed plastic shell with branch pipe in flange, flange wound with composite material with support surface and a hole with a nozzle installed in it with a threaded hole and a device with adjustment of the sealing degree of the branch pipe by changing the pressing force of the seal to the sealed surfaces. Sealing device of branch pipe is equipped with nut made with cylindrical surface of diameter equal to inner diameter of seal, and with external thread corresponding to thread of nozzle, and equipped with shaped hole for screwing nut into union, and flange with diameter equal to diameter of hole of branch pipe. Seal is arranged between union end and nut flange. Bore end is equipped with bore diameter equal to diameter of nut cylindrical surface.
EFFECT: technical result consists in improvement of durability and simplification of balloon manufacturing technology.
