Teleflex Seastar inboard hydraulic steering cylinders are engineered and manufactured for most pleasure and commercial vessel applications up to 38 feet in length. Cylinders are constructed from regular duty aluminum and heavy duty brass.
SeaStar cylinders are easy to install for single and dual rudder systems, feature two axis articulation, and can be easily interfaced with an autopilot system. All cylinders are supplied with bleeder fittings for easy maintenance.
Brass Cylinder Dimensions: 21" x 8.0" x 10.0"
Aluminum Cylinder Dimensions: 20" x 6.5" x 8.5"

When you are installing new steering system and autopilot system, pump specification indicates IE 1.2 Lt, 2.0Lt, etc. How do you know which pump is to be used for certain HYD. steering cylinder. thanks.
It depends on the size and displacement type of the boat, larger boats require more force to move the rudder.

I need a seal kit for a teleflex cylinder ram with a 1" shaft diameter? I can't read the model #. The cylinder was installed on a 2014 boat. Thanks. Nick
The seal kits are specific to the cylinder model. If you don't have a part number on the cylinder, go on our website and search on hydraulic cylinders to see if there is a picture of what you have, you will need a seal kit for that part number.
Brass V Alum ?
Brass will not oxidize like aluminum will in time. It may turn green but will last longer than aluminum.
good product, great service!
Bleeding the system was a bit messy but all's well that ends well!

Very complete kit, well made
I bought an HC5312-3 hydraulic cylinder to replace my original, 2005 vintage, cylinder which had started to leak and I couldn't repair. The kit is complete with a helm fluid fill kit and bleeder hose. The materials and instructions are excellent. It takes two people to bleed the system but it is not hard to do. The original cylinder failed due to rust preventing the "rod ball end" from moving which caused the piston seal to wear and leak. The new cylinder appears to have several design improvements and works well. The instructions don't mention it but I greased the moving parts of the "rod ball end" to try to prevent future corrosion.
