50mm Tow Ball Hydraulic Coupler
This 50mm American hydraulic coupler replaces 2″ non-compliant American boat trailer, RV, trailer, caravan couplings.
Approved to Australian Standards Compliant AS4177.3
The bleed pump screw is located under the coupling and when activated, pumps hydraulic oil through the hoses to the calipers. The bleed screw pump allows pressure to be applied to the hydraulic system to enable each caliper to be bleed.
This high-quality hydraulic actuator rated to 2000kg and suits tandem hydraulic setups or 2000kg single axle setups.
Note: One axle only requires hydraulic calpers.
The actuator fits either American calipers or Australian calipers.
The hydraulic coupler includes a reversing switch that is connected to the tow vehicle reversing lights. The purpose of the reversing switch is to disengage the hydraulic braking system while reversing.
