SeaStar HP6013 Stainless 5/8" Rod End Ball Joint for Marine Steering Cylinders
The SeaStar HP6013 is a high strength Stainless rod end ball joint type used on SeaStar hydraulic steering cylinders. The threads measure 5/8" and the ball joint is 5/8".
Original cylinder references:
- HC5319-3 and HC5373-3: manufacturer parts tables identify HP6013 as the original rod-end reference.
- Legacy references: HC5319, HC5319CAT, HC5373, HC5350 and HC5351.
- Match both dimensions: HP6013 has a 5/8-inch mounting eye and a 5/8-18 UNF female thread.
- Different original rod end: factory tables list HP6093 for HC5318, HC5318CAT, HC5369 and HC5349. HP6093 also has a 5/8-inch eye, but its female thread is 1/2-20 UNF.
- Confirm the exact cylinder model, generation and installed hardware before ordering. A complete-cylinder replacement reference does not establish rod-end interchangeability.
