This is a Panasonic self-supporting resin pipe shut-off valve. It's a shut-off valve for toilet poly pipes, and Panasonic offers it as the "for Arauno" model from KVK. However, since an angle stop valve is included in the ④ connection fitting, it can be connected and used with any manufacturer and type if it's a 13mm water supply hose connection type. Anyone can install it easily, quickly, and neatly. Installation instructions and a construction manual are included, so you don't have to worry!
