Hydraulic Steering Fluid

Our Hydraulic Steering Fluid range covers the specific fluid used to top up or bleed hydraulic steering systems – not interchangeable with general hydraulic or brake fluid, since marine steering systems specify their own fluid type.

Always use the fluid type specified by your steering system’s manufacturer rather than a generic hydraulic fluid, since using the wrong type can damage seals or affect how the system performs, and manufacturers are specific about this for good reason. A hydraulic steering system that feels spongy or has lost some responsiveness often needs bleeding and topping up rather than a full component replacement, so check fluid level and condition before assuming a bigger fault. If you’re not confident bleeding a hydraulic steering system yourself, given that steering is safety-critical, it’s worth having a qualified rigger or engineer check it.

Frequently asked questions

Can I use general hydraulic fluid in my boat’s steering system?

No – always use the fluid type specified by your steering system’s manufacturer, since the wrong type can damage seals or affect performance.

My steering feels spongy – what does that usually mean?

Often points to air in the system needing bleeding and topping up, though given steering is safety-critical, it’s worth having it checked if you’re unsure.
