Hydraulic oil expansion tank

The hydraulic oil reservoir is an important component of hydraulic power steering systems and serves to store and equalize the hydraulic oil in the steering circuit. It ensures that there is always sufficient hydraulic fluid in the system and supports a consistent supply to the power steering pump.

The reservoir is usually mounted in the engine compartment and connected to the power steering pump and steering gear via hoses. During operation, the hydraulic fluid circulates through the system and is collected in the reservoir before being returned to the pump. Many reservoirs are equipped with integrated filters that remove contaminants from the fluid, thus extending the service life of the power steering components.

Hydraulic oil reservoirs are typically made of robust plastic or metal and feature a tightly sealing cap with an integrated venting system, as well as a level indicator or markings to monitor the oil level. A damaged or leaking reservoir can lead to hydraulic oil loss, air in the system, or reduced power steering.

In this category, you'll find hydraulic oil expansion tanks for numerous vehicle makes and models, available in perfect original equipment manufacturer (OEM) quality or as high-quality aftermarket alternatives.
