Phonak & Unitron hearing aid SlimTubes SDS 4.0

These tubes are used on Phonak and Unitron hearing aids.

Left tubes are marked in blue and right tubes are marked in red, the length of your tube is the number; so 3L is length three left side.

Helpful Note: Slim tubes come in a variety of sizes. Please be sure you know the exact size/model you require before placing your order.

If you're not sure which ones you need, please don't guess as you're likely to be wrong! Please talk to your audiologist to confirm the correct type before placing your order.

Please note for hygiene reasons these products are excluded from the Connevans extended returns policy. Once you open the packet we will not accept them for return /credit as we cannot resell them - the packets are clear so it is easy to check the markings before opening.
