Complete set Backhoe loader hydraulic rock breaker piping kits fit Caterpillar 416 420 436 , with flow divider valve
Backhoe loader Cat® 416 Cat® 420 Cat® 436 aux hydraulic hammer pipeline
Upgrade your Caterpillar backhoe loader with our premium auxiliary hydraulic piping kit. Specifically engineered for CAT 416, 420, and 436 series, this complete set allows you to seamlessly operate hydraulic rock breakers, hammers, and other one-way attachments.
The standout feature of this kit is the Integrated Flow Divider Valve (Priority Valve), which ensures your breaker receives the exact hydraulic flow required, protecting your attachment from over-speeding and overheating while maintaining the loader’s overall hydraulic efficiency.
Key Features & Technical Advantages
Precision Compatibility: Custom-bent steel tubes and high-pressure hoses designed to follow the exact contours of the CAT boom and stick for a factory-clean installation.
Integrated Flow Divider Valve:
Protection: Regulates the high flow from the backhoe’s main pump down to the specific requirements of the hammer.
Stability: Prevents hydraulic pressure spikes and ensures a consistent strike rate for the breaker.
Heavy-Duty Construction:
Steel Piping: Phosphated, anti-corrosion treated seamless steel tubes.
Hoses: Four-wire braided high-pressure hydraulic hoses rated for extreme vibration and heat.
Complete Installation Set: No need for extra sourcing. Includes all mounting clamps, bolts, brackets, ball valves, and quick-release couplers.
