SORRY this original type of tubing, for the Swing breast pump is now discontinued.
The good news, we have other upgrade options which are compatible with your original motor. There is a new option in the Swing Flex Tube, though you will need to get the Flex Connector so that it will connect with your pump, as it does not fit with the original elbow.
The price is for 1 piece.
Read Franny's Blog Here which gives a summary of the Swing Breast Pump parts (and versions) so you can make sure you are buying the correct tube.
