Thin tube adapters for Beltone hearing aids
Thin tube adapters connect the thin tube to the hearing aid body on compatible Beltone BTE hearing aids. This small component helps keep the tube securely in place and forms part of the sound path that carries amplified sound from the hearing aid into the ear.
In this category, you can find the ThinTube Adapter B70 with integrated filter for selected Beltone BTE hearing aids. It is a practical replacement part when the original adapter becomes worn, damaged or blocked.
What is a Beltone thin tube adapter?
A thin tube is a hollow sound tube used with certain behind-the-ear hearing aids. The sound is produced inside the hearing aid and travels through the tube towards the ear. The adapter sits at the hearing aid end of this fitting and provides the connection between the device and the thin tube.
The B70 adapter also includes an integrated filter, which helps protect the sound path against dirt and other debris. Keeping this connection clean and intact helps support reliable sound transmission and a secure thin-tube fitting.
Beltone BTE hearing aids with thin tubes
Beltone has offered BTE hearing aids that can be fitted with thin tubes and domes. These systems provide a slimmer alternative to traditional thicker earmould tubing while still keeping the speaker inside the hearing aid body.
The exact adapter depends on the hearing aid model and fitting system. A B70 adapter should therefore only be used with Beltone hearing aids designed for this particular connection.
ThinTube Adapter B70 with filter
The ThinTube Adapter B70 with filter is a connection component for selected GN BTE thin-tube systems. It keeps the tube securely connected to the hearing aid and includes an integrated filter for additional protection of the sound path.
For Beltone hearing aids, the B70 adapter is compatible with selected BTE models including:
- Beltone Achieve BTE 76
- Beltone Achieve BTE 77
- Beltone Imagine BTE 76
- Beltone Imagine BTE 77
If you already use a B70 adapter, replacing it with the same adapter type is the easiest way to ensure that the connection continues to match your thin-tube fitting.
When should the adapter be replaced?
The adapter is exposed to everyday wear and forms part of the route through which sound passes. Over time, the integrated filter may collect dirt or become blocked, while the connection itself can become worn.
If the sound becomes weaker or the tube no longer connects securely, inspect the adapter as well as the thin tube and dome. Replacing a worn or blocked component can help restore a secure fitting and clear sound transmission.
Taking care of Beltone thin tubes
Beltone recommends cleaning thin tubes regularly to remove moisture and skin oils. Thin tubes and domes should also be replaced when they become stiff or brittle. Keeping the complete fitting clean – including the tube, dome and adapter – helps maintain comfort and reliable everyday performance.
Always make sure the thin tube and adapter are properly connected before wearing the hearing aid again.
