FAQs

What is the Dometic SeaStar HP6019?

The Dometic SeaStar HP6019 is a stainless steel rod end ball joint used on select SeaStar hydraulic steering cylinder applications. It features 3/4"-16 FNF threads and a 3/4" hole, and is commonly used with HC5801-2 and HC5803-2 cylinders.

Is HP6019 a tie bar end or a cylinder rod end ball joint?

HP6019 is generally described as a SeaStar rod end ball joint and is also referenced in tie bar-related applications on compatible steering setups. The safest way to confirm usage is to match your cylinder model, thread size, and hole diameter before ordering.

How do I confirm HP6019 will fit my steering system?

Start by confirming your steering cylinder model. Then verify that your existing part matches the 3/4"-16 FNF female thread and 3/4" hole dimensions. SeaStar owners on boating forums often identify replacement ball joints by exact thread and bore size, so matching dimensions is important.

What cylinders is HP6019 commonly used with?

HP6019 is commonly listed for HC5801-2 and HC5803-2 SeaStar cylinders.

What are the signs that a steering ball joint should be replaced?

Replace a steering ball joint if you see corrosion, binding, looseness, excessive play, or visible wear. Dometic advises checking for binding, loose, worn, or leaking steering components and not operating the boat if any steering component is not in proper working condition.

Can I replace just the ball joint instead of the entire tie bar assembly?

In some SeaStar applications, yes - individual replacement ball joints like HP6019 are available. However, forum discussions show that on some older or different tie bar assemblies, owners end up replacing the full assembly when the exact end component is difficult to identify or source. Always verify the exact steering and tie bar setup before ordering.

Is a small amount of steering drift or movement normal?

A small amount of hydraulic drift can be normal in SeaStar hydraulic steering systems. However, corrosion, binding, or looseness at the ball joint is not considered normal and should be inspected promptly.

How should I maintain the HP6019 ball joint and surrounding steering hardware?

Rinse the steering system with fresh, clean water after use, avoid corrosive cleaners, and inspect the steering components regularly for looseness, wear, leaks, or corrosion. Dometic also recommends maintaining the steering system at least twice per year.

Do I need to recheck tie bar alignment after replacing a ball joint?

If the ball joint is part of a tie bar-linked setup, it is smart to recheck alignment and steering travel after installation. Boat owners frequently ask about tie bar adjustment after cylinder or linkage work, so confirming smooth articulation and proper engine alignment is a good final step.
