  • Hose bands, which are used in LPG (Liquefied Petroleum Gas) or LNG (Liquefied Natural Gas) facilities for home use to join low pressure hoses with fuse-cocks (or regulators), should give a tight connection to prevent a gas leakage from hose connection parts. In this paper, hydraulic pressure tests and pull force tests were carried out to evaluate the performance and swaging length of hose bands. Experimental results showed that the swaging force of ear type bands were higher than those of spring bands and also showed that the optimal swaging length was about 1${\~}$2 mm from the hose end.
