Breather tubes can be incorporated into cables:

• To allow submersed cavities, sensors and trasmitters to "breathe" to the atmosphere, or
• Transport inert gases in closed systems.

The breather tube is designed not to crack when subjected to cold bend and mechanical tests typically specified for the cable.

The breather tubes must not be kinked. Therefore, the minimum bend radius is 10X the cable outer diameter.

Do NOT bend a cable with a breather tube around sharp corners.
