Flexible water connector (flexible connector) — a non-rigid tube or hose with end connections used for connecting a water supply to a fixture, fitting, or appliance. Push-fit fitting — a mechanical fitting that joins pipes or tubes and achieves a seal by pushing the mating pipe or tube into the fitting by hand. The fitting can be removable or non-removable.
