This is a genuine Hitachi water supply hose! It can be installed on any washing machine, whether top-loading or drum-style! Other manufacturers' standards are the same, so it will fit without any problems. (It seems that some Haier and Hisense models may not fit depending on the model number.) Both the attachments and packing are hardly deteriorated, so they are ready to use immediately! Water supply hoses can be easily replaced with a single touch, so why not replace them regularly for washing machine maintenance?
