Differences Between the HydraStar Hydraulic Actuators for Disc Brakes


What is the difference between the Marine Vented Hydrastar, and non vented controller. What does the ventinch do. Regards


Expert Reply:

The HydraStar Marine Electric Over Hydraulic Actuator w/ Breakaway and 7-Way RV Harness item # HS381-9067 is designed to work with an aftermarket electric over hydraulic brake controller.

The HydraStar Vented Marine Electric Over Hydraulic Actuator for Disc Brakes - OEM item # HS481-8067 will allow you to use a OEM brake controller to operate the trailer brakes.

If your vehicle has an aftermarket brake controller you will want item # HS381-9067. If you have a vehicle that came from the factory with a brake controller you'll need item # HS481-8067. Both of these actuators are designed only for disc brakes.

The vented end plate releases pressure, moisture, and heat in order to protect the internal components.
