These are replacement tubes for the Hear Clear HCZ1 or HCZ3 Hearing Aids only.
There are 2 tubes per package.
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 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 a sample pack. 888-570-2740
