Specs At A Glance

Good To Know

Q: How do I know if my cylinder needs a seal kit? A: Common signs are fluid weeping around the cylinder, a spongy or drifting helm, and loss of steering pressure. If you see any of these on a SeaStar HC5345 or HS5157, a seal kit is the usual fix.

Q: Is any special tooling required for the rebuild? A: Basic hand tools and a clean work area are typically enough, but take care with seal orientation and avoid nicking the new seals. Bleeding the system after reassembly restores full steering response.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
