Perform under pressure


Protect your hydraulic system with genuine Cat® parts and achieve maximum performance throughout the life of the machine.

Your Cat® hydraulic system is designed to withstand high pressures to meet the demands of your machine. Contamination and component damage can lead to reduced efficiency and unplanned downtime. That’s why a well-maintained hydraulic system is critical for achieving maximum performance and value for the life of your machine.

Every component in your hydraulic system is vital for the performance of your operation, and it all relies on the ability to perform under pressure.

“Genuine Cat parts are uniquely designed for enhanced performance, durability and seamless integration in a highly refined hydraulic system,” Caterpillar Hydraulic Component Application Specialist Fabrice Trolio said.

“That’s why it’s critical that you always use genuine Cat parts.”

There are three main component groups to consider: hoses and couplings, cylinders and rods, and pumps and motors.

The Cat hydraulic system can withstand high pressures to meet the demands of your machine.

Cat hoses and couplings

Designed for durability and corrosion resistance, genuine Cat hoses and couplings deliver industry-leading flexibility and can help increase machine reliability and safety. Cat hoses and couplings are tested together as a system to provide maximum performance in a wide range of applications.

Cat cylinders and rods

Genuine Cat cylinders and rods help deliver the optimal balance of strength, surface finish and impact resistance. Cylinder seals are bore-skived and roller-burnished for superior sealing performance. The components work together to help ensure greater resistance to contaminants.

Cat pumps and motors

Genuine Cat pumps and motors are built to tight tolerances and are tested to match stringent Cat hydraulic system performance and endurance requirements. These components are tuned to your machine’s unique controls and settings to help optimise performance and maximise equipment productivity.

Don’t wait for failure

It’s so important to keep your eye on your hydraulic system efficiency. It can erode significantly before you notice a problem. That’s why it’s vital to help avoid failure by conducting proper maintenance – and relying on the support of your local Cat dealer.

There are three key maintenance areas to consider: prevention, detection and inspection.


  • Conduct regular maintenance by changing and monitoring oil, performing daily inspections and looking for signs of wear and tear
  • Learn the causes and effects of contamination


  • Scheduled oil sampling (S•O•SSM) services are provided by your local Cat dealer to help detect hydraulic system issues
  • Help improve your scheduling of downtime and budget management by predicting your machine’s repair needs


  • Check for leaks and don’t ignore excessive noise or vibration
  • Inspect your machine for signs of damage, loose or missing hardware, and to help monitor hydraulic system cycle times and drift rates
Cat pumps and motors are tested to match stringent the hydraulic system’s requirements.

Again, it’s always a good idea to listen to the advice of experts. On the benefits of repairing before failure, Trolio said, “It helps reduce costs for the customer. You’re able to plan downtime and avoid the high costs of repair after a failure has occurred. Dealers can provide a range of detection services to support the before-failure approach, such as S•O•SSM Services analysis.”

Hydraulics are the lifeblood of your business, and there’s almost no hydraulics issue that your Cat dealer hasn’t dealt with before. So make sure you make them your first port of call.
