Full Product Description
The SeaStar HS5157 Seal Kit (by Dometic) is a high-quality OEM replacement kit engineered to withstand the rigors of harsh marine environments. When hydraulic cylinders begin to leak, steering responsiveness and safety are compromised. This kit allows you to rebuild the cylinder ends rather than replacing the entire unit, saving you significant time and money.
Constructed from marine-grade anodized aluminum and high-precision rubber O-rings, the components ensure a snug, leak-free fit. The included pin wrench (spanner) is a critical tool required to remove the threaded end glands without damaging the cylinder body. Whether you are performing routine maintenance or an emergency repair, this kit ensures your steering remains smooth and reliable.
