197-6218 Accumulator Group
Cat® Accumulator Group (Refrigerant)
Description
An accumulator is a pressure storage vessel that a hydraulic system can use to manage extreme system demands. By storing pressure in the accumulator, the hydraulic system can use a lower-power pump to meet urgent, temporary pressure demands.
Warning: Always consult MECHSC on how to properly release accumulator system pressure before servicing an accumulator. Improper handling may result in injury or death.
Features
- Refrigerant accumulator
- Inlet and outlet: 1-1/16-28 UNF O-ring port

Applications
Cat® accumulators are versatile, for example in hydraulic systems, where they enable the system to manage pressure surges, a condition that can produce enormous loads. They can also be used in brake systems and suspension systems.
