FIELD: storing or distributing liquids or gases.

SUBSTANCE: vessel comprises threaded neck, valving system with threaded part to connect it to the neck, and device for the relief of pressure when assembling mounted on the threaded part of the valving system. The seal is made of a polymeric composition and is set in the spiral space between the turns of the vessel neck over the section between the outer face of the threaded neck to the device for pressure relief to define a glue connection. The method comprises mounting valving system with the cylindrical threaded section to the threaded neck of the metallic vessel and sealing the cylindrical threaded connection. The valving system is screwed in the neck with an arbitrary torque with the use of a lubricant made of an anaerobic glue that is applied on the turns of the thread or turns at any site of the threaded section. The assembled joint is allowed to stand at a temperature no less than 5°C over at least 20 min.
