Contamination Control

Our Little Rock Hydraulic facility is climate controlled to minimize the opportunity for contamination. With the current sophisticated hydraulic systems that are designed with ultra – tight design specifications, any intrusion by contaminates can cause catastrophic
failures or greatly reduce system life. We have stringent standards of cleanliness that we adhere to in order to minimize, with the intent to eliminate, component killing contaminates.


When it comes to valves for your construction equipment, the Riggs Cat team has the knowledge, parts and repair capability that will save you time and money. All parts will be tested before re-installation.

Hydraulic Testing

All components that Riggs CAT rebuilds or refurbishes are tested. Our technicians will not send a cylinder, pump, or motor back to the field without first being performance tested. We pressure test hydraulic cylinders at normal system pressure – not just testing the seal. Our pump and motor test bench allows us to simulate machine or system operations and functions.

We have 24 hour 7 days a week service availability.
