Streamline Your Autopilot Setup with Precision Engineering
Installing an autopilot hydraulic system on your vessel can be a game-changer for long hauls and effortless navigation, but getting the plumbing right is crucial to avoid leaks, pressure drops, or system failures mid-voyage. This pre-assembled hose fitting kit transforms a potentially frustrating task into a straightforward process, tailored specifically for ORB steering systems paired with Simrad MK2 pumps. By delivering factory-crimped hoses and robust connectors, it minimizes the risks associated with custom field terminations—like air pockets or mismatched fittings—that plague many DIY marine installs.
Key Advantages for Boaters and Installers
-
Leak-Proof Reliability: Pre-made hoses with high-pressure ratings ensure a secure seal, reducing downtime and maintenance hassles on the water.
-
Time-Saving Design: No need for specialized crimping tools or guessing hose lengths—everything fits perfectly for pumps 1 through 5, covering a wide range of boat sizes from tenders to larger cruisers.
-
Professional-Grade Results: Achieve OEM-quality connections that stand up to the rigors of saltwater exposure, vibrations, and constant hydraulic cycling.
-
Complete Starter Package: Includes essential fluids and tools to get your system primed and running without extra trips to the supplier.
Everything You Need in One Kit
Crafted for compatibility with ORB (O-Ring Boss) hydraulic steering setups, this kit provides all the interconnects required between your MK2 pump and steering ram. Each component is selected for durability and precise fitment, helping you maintain optimal system pressure for responsive autopilot performance.
- Two T-connectors: ORB-05M to dual 9/16-24 UNF threads for seamless branching.
- One right-angle connector: ORB-05M to 9/16-24 UNF, ideal for tight helm spaces.
- Two black high-pressure hoses: 5/16-inch diameter, 1500 PSI max, 750 mm length with 9/16 UNF to 9/16-24 UNF ends—perfect for main pressure lines.
- One clear low-pressure hose: 5/16-inch diameter, 65 PSI max, 750 mm length with 9/16 UNF to 9/16-24 UNF ends—for return lines with easy flow monitoring.
- Hydraulic fluid bottle: The right viscosity for smooth pump operation and corrosion protection.
- Filter funnel: Prevents contaminants during fill-up, extending component life.
Effortless Installation Tips from Marine Pros
Whether you're retrofitting an older helm or setting up a new Simrad autopilot, this kit shines in confined engine spaces or consoles. Start by routing the high-pressure black hoses from pump ports to your steering cylinder via the T-connectors, using the right-angle fitting to dodge obstructions. The clear return hose loops back effortlessly, while the included funnel ensures a clean fluid top-off. Pro tip: Flush the system thoroughly before powering on to eliminate any manufacturing debris, and always bleed air from the highest points for jitter-free steering.
Compatibility Snapshot
Engineered for Simrad MK2 pumps (1, 2, 3, 4, and 5), this kit pairs flawlessly with popular RPU-series pumps used on vessels from 24-foot day boats to 50-footers. It's a must-have for ORB-equipped rams from brands like SeaStar or Teleflex, ensuring your autopilot delivers pinpoint course-holding even in choppy conditions.
Long-Term Performance and Care
Beyond installation, this kit supports ongoing reliability. The color-coded hoses make inspections a breeze—check black lines for pressure integrity and the clear one for fluid clarity. Regularly inspect O-rings for wear, and top off with the matching hydraulic fluid to prevent pump cavitation. Boaters report fewer service calls and smoother operation after switching to pre-fitted setups like this, turning potential headaches into set-it-and-forget-it convenience.
Frequently Asked Questions
What pumps is this fitting kit compatible with?
This kit is designed for Simrad MK2 pumps 1, 2, 3, 4, and 5, making it suitable for a variety of vessel sizes in ORB steering systems.
Do the hoses come pre-assembled or do I need to crimp them?
All hoses arrive factory-assembled with crimped ends, eliminating the need for tools and reducing leak risks from field fabrication.
What's the difference between the black and clear hoses?
Black hoses handle high pressure up to 1500 PSI for supply lines, while the clear hose is rated for 65 PSI returns, allowing visual checks for air bubbles or contamination.
Is hydraulic fluid included, and what type is it?
Yes, a bottle of compatible hydraulic fluid is provided, formulated for marine autopilot systems to ensure proper lubrication and system protection.
Can this kit be used with non-Simrad steering rams?
It works with any ORB-threaded hydraulic steering ram, such as those from common marine steering brands, as long as fittings match 9/16-24 UNF standards.
How do I bleed air from the system after installation?
Fill the pump reservoir using the filter funnel, cycle the helm from lock-to-lock several times with the engine off, then run the autopilot in calm water to purge remaining air.
Fitted hose kit designed for simplified ORB system installation reducing the opportunity for faulty field terminated hydraulic hoses and incorrect installation layouts.
