Hydraulic oils — the right fluid for hydraulic steering

In the Hydraulic Oils product group you will find hydraulic steering system filling fluids: Ultraflex hydraulic oil OIL 15 (1L), Mobil hydraulic oil ATF 320 (1L), Glydus hydraulic oil (1L), Quicksilver hydraulic oil (1L) and SeaStar hydraulic oil, and also an Ultraflex filling kit for adding oil to the system.

Unlike separate hydraulic pumps and cylinders (product group Hydraulic pumps and cylinders) and hydraulic hoses, this section focuses solely on the hydraulic fluid itself — all of the above components require the correct oil suitable for their system to function.

The type of oil is not irrelevant: Ultraflex, SeaStar and Uflex systems may require slightly different viscosity and seal compatibility, so it is always a good idea to check the manufacturer's recommendation for your steering system before filling — the wrong oil grade can swell or shrink seals over time, leading to leaks and loose steering.

Filling is always done through the system's own filling kit, and air should be carefully removed from the lines after filling — air in the hydraulic system causes a soft, "spongy" feel in the helm and reduces steering accuracy. Check the oil level regularly during the season and top up if necessary, as a small decrease in oil is normal, but a rapid drop in the level indicates a leak that should be checked immediately.

Keep the opened oil container tightly closed, as hydraulic fluid can absorb moisture from the air over time, which will degrade its properties — outdated or water-containing hydraulic fluid can cause corrosion in the system's internal components. Replace the fluid completely at the manufacturer's recommended intervals, don't just add to the old fluid if you notice any signs of cloudiness or discoloration.

If you notice unusual stiffness or looseness in the steering, check the oil level first before taking any further action — often a simple oil top-up or complete oil change will solve the problem without the need for a more expensive repair.

Make a note of the type and brand of oil used so that the next fill or change is always done with the same, compatible fluid — mixing different types of oil can impair system performance over time.

Compare the compatibility of different hydraulic fluid brands according to your system manufacturer's recommendations before the first fill or complete fluid change.

Always keep a filling kit with you on the boat so that you can quickly add a small amount of oil during the trip if necessary.

If necessary, seek advice on choosing the right oil grade if the manufacturer or model of your steering system is unclear.

Check the seal on the filling kit before use to prevent any spillage or unnecessary waste during filling.
