do you have water proof actuators.
Not many actuators are waterproof, and waterproof ratings tend to be specific (IP##)
We offer a variety of RC servos which are waterproof to 1m:

For linear actuators, the following rubber boot helps make specific Firgelli linear actuators water tight, but they cannot be submerged completely:

Unfortunately we do not have actuators specially for ROVs if that is your intended use.
