With this adapter, you can connect your dishwasher, washing machine, dryer, and the drain of your kitchen or bathroom sink. To prevent water leaks, each unit has a gasket and a clip for one outlet, and two clips for two outlets. The drain hose is easy to install and is manually connected to the nozzle and secured with a clamp/clip. The drain hose can only be installed manually. The clips/clamps only require a screwdriver. Adapter Design: The inlet and outlet are arranged at a 45-degree angle to avoid clogging drainage while occupying a small space. Size: The size and fit are designed to be optimal. For most washing machine and dishwasher hose outlets, the ideal size is 19-24mm, while the outlet diameter for siphons is 40mm.
