Continuous Flow Adaptor (CFA®)

The Continuous Flow Adapter is a unique patented product designed by Pacific Coast Laboratories, Inc. The CFA® adapter and its connected tubing maintain the internal diameter of the the tubing between a BTE and the ear mold, providing a continuous, unimpeded flow of amplified sound.

The CFA® is a hard plastic "elbow" which is held in an ear mold made of soft material with a barb-like end. Once inserted into the ear mold, the CFA® (and the tubing attached to it) can swivel as needed without coming out of the ear mold.

Key benefits include:

Other ways of attaching the tubing to the ear mold include:

Gluing presents a maintenance problem since it can be difficult to remove or replace the tubing. It also prevents the tubing from turning within the ear mold once the glue is set.

The pressure fit and the use of a little metal clip can also limit movement and make future changes difficult, but these can also change the acoustic properties of the tube by compressing the tubing as it enters the ear mold.

A CFA® can help solve these problems.
