SeaStar HS5167 Front Seal Kit for Pivot & Front-Mount Steering Cylinders — 2 Seal Glands + Guide Tool

If your boat’s steering cylinder is leaking or showing signs of wear, replacing the front seals restores smooth, reliable steering operation and helps prevent fluid loss. The HS5167 kit supplies the specific seal glands used on a wide range of SeaStar front-mount cylinders and includes a simple assembly guide tool to speed installation. SeaStar has supplied marine steering components for nearly six decades, so these parts match original specifications for fit and function.

Which cylinders will this seal kit fit?

The HS5167 front seal kit is made for SeaStar pivot and front-mount cylinders and fits many specific part numbers used across the brand’s steering lineup. It’s built to match the original gland dimensions so you won’t need to modify the cylinder housing. Installing the correct gland set restores the cylinder’s sealing surface and reduces the chance of future leaks when installed properly.

• Compatible front-mount parts include HC5340, HC5341, HC5342, HC5343, HC5344, HC5345, HC5346, HC5347, HC5348.
• Also fits HC5358, HC5365, HC5375, HC5394, HC5445 plus HC6750–HC6755 models.
• Includes two seal glands sized to OEM specifications for a direct replacement.

What’s included and how does the guide tool help?

The HS5167 package contains two replacement seal glands and a seal gland assembly guide. The guide tool helps align and seat the glands correctly, reducing installation time and lowering the risk of damaging the seal during reassembly. With the guide, both experienced technicians and capable DIYers can achieve a cleaner, more reliable seal installation.

• Contents: (2) seal glands and one seal gland assembly guide tool.
• Guide tool ensures proper seating and alignment for leak-free reassembly.
• Spares are precision-made to match SeaStar factory tolerances.

How long does the replacement take and what tools are required?

Service time varies by experience and access, but a competent technician can usually complete the front-seal replacement in a short workshop session when the cylinder is accessible. The HS5167 kit does not include a wrench; you’ll need standard hand tools and possibly a press or mallet for seating, depending on the cylinder design. Use the included guide tool to minimize trial-and-error and protect the new seals during installation.

• Typical install time: moderate—often under an hour with the cylinder removed.
• Required tools: common hand tools; specialist press or mallet may be needed for some cylinders.
• Wrench not included—purchase appropriate tools if you don’t already have them.

SeaStar products carry a two-year recreational user warranty against manufacturing defects, so you get both the correct parts and warranty protection when replacing worn seals. Always follow SeaStar’s installation guidance and inspect related components (rod, barrel, and fittings) while the cylinder is open to decide if further service is needed.

Who is this for? Boat owners, marine technicians, and service shops maintaining SeaStar pivot or front-mount steering cylinders that match the listed part numbers. Choose the HS5167 kit when you need factory-fit front seal glands and a simple alignment tool to restore steering reliability without replacing the whole cylinder. This is intended for non-commercial recreational vessels covered by SeaStar’s two-year warranty policy; if you’re unsure about fitment, check your cylinder part number before ordering.
