There are 2 tubes per package (one side only). If you need tubes for both sides you will need to choose BOTH and purchase 2 packages.
The higher the number on the tube, the longer the tubing will be. If you currently have tubes, the size you need will be printed in blue or red on the end where the dome connects. You should also see a 0.9mm or 1.4mm size as well. (You may need a magnifying glass and good lighting to see this).
Note: All Tube orders are non-refundable if opened. If you are not certain of your size, call us about purchasing a sample pack. 888-570-2740
