Ensure your helm system is equipped with ORB-compatible fittings (e.g. SeaStar HF6009, HF6010, HF6011, or HF6012). Older NPT-based systems are not compatible without upgrading the fittings.\u003c\/p\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e The HC5370-3 is the right choice for side mount outboard steering applications where the splashwell depth is shallow or the engine is fitted with power steering. It's a solid upgrade path from older NPT-based cylinders — just confirm your helm lines use ORB fittings before installing.
