Correct disposal of used steering fluid and componets. Please place contaminated materials in disposable containers and dispose of in a manner consistent with applicable regulations. Contact local environmental or health authorities for approved disposal of these materials. Thank you!

SeaStar hydraulic steering systems require the use of a special high quality hydraulic fluid meeting MIL SPEC H-5606 C. This fluid is available in 1 liter (33.8 US fluid ounce) bottles as:

SeaStar Hydraulic Fluid:
Part Number HA5430 - 1 Liter
Part Number HA5440 - 4 Liters

Alternate recommended hydraulic fluids for SeaStar steering systems

Substitution of non-recommended fluids may result in heavier steering and/or irreparable damage to your steering system.

Never use brake fluid. Any non-approved fluid may cause irreparable damage, loss of steering, and cancellation of warranty.

In cases of emergency automatic transmission fluid Dexron II may be used. In cases of extreme emergency any nontoxic, nonflammable fluid may provide temporary steering.

Replacing or upgrading from a Syten inboard steering system to SeaStar Components.

Helms: The Syten helm pump should be replaced with the current model SeaStar Helm Pump HH5271 and Back mount kit HA5418. This should be done at each helm station.

Tube: The 5/16 nylon tube and fittings are obsolete and must be replaced with SeaStar 3/8" nylon extruded tube for all inboard applications.

Uniflow Valve: U-10 or Model 50: Obsolete, no replacement parts are available.

Cylinder: Adapter HA5425 is required for the conversion from a Syten steering cylinder to a current SeaStar Steering cylinder.

The Syten components were produced up until late 1984 when they were replaced by the SeaStar Steering systems.Teleflex Canada no longer stocks any replacement parts, fittings or seal kits for this steering system or any component of this system.
