This tubing is denser material because it lessens or prevents moisture from forming inside the tubing. Great for humid environments. If you have problem with moisture clogging the tubing in your BTE hearing aids, this may be the solution. Choose from tint or clear color.

Quilled end (pointed) for easy insertion.

4 tubes per order.
