SeaStar Front Seal Kit HS5167 — seal glands & guide tool for front-mount/pivot steering cylinders (no wrench)

SeaStar HS5167 is a front-seal replacement kit containing two seal glands and the guide tool made to service SeaStar pivot and front-mount steering cylinders.

When steering components start to weep or show play, replacing worn front seals restores proper hydraulic containment and helps maintain smooth steering feel. The HS5167 kit from SeaStar (Dometic SeaStar line) supplies the exact seal gland parts and an assembly guide tool designed to fit a range of front mount cylinder models so you can service your existing hardware without replacing the whole cylinder.

Which SeaStar cylinders will this HS5167 kit fit?

This kit is built to match SeaStar front-mount and pivot cylinder front seals used across many OEM and aftermarket steering assemblies. Verify your cylinder part number against the included compatibility list before ordering to ensure a correct match.

• Compatible with front-mount/pivot cylinder part numbers such as HC5340–HC5348, HC5358, HC5365, HC5375, HC5394, HC5445, HC6750–HC6755.
• Designed for SeaStar hydraulic steering cylinders that use the same seal gland geometry.
• Not a universal seal kit; cross-reference your cylinder part number or consult SeaStar technical documents.

What exactly comes in the HS5167 seal kit?

The HS5167 shipment contains the components needed to replace the front seal assembly on compatible cylinders. The kit focuses on the front-end sealing components so technicians can refresh the pressure and rod seal surfaces.

• Two replacement seal glands sized for SeaStar front mount/pivot cylinders.
• A seal gland assembly guide tool to aid correct installation and alignment.
• Packaged for service techs and DIYers who already have the basic cylinder disassembly tools (note: wrench not included).

How does the assembly guide tool help during installation?

The included guide tool simplifies seating the new seal glands straight onto the cylinder rod and into the bore, reducing the risk of misalignment or seal damage during installation. It’s intended to make service faster and cleaner when replacing front seals.

• Aligns and centers seal glands for uniform seating and consistent sealing surfaces.
• Reduces handling of fragile seals, lowering the chance of nicks or folds.
• Speeds up assembly compared to hand-pressing seals into position.

SeaStar backs its products with a two-year recreational-user warranty against manufacturing defects, giving installers and owners a defined period of coverage for workmanship-related problems. Remember to keep proof of purchase and follow recommended installation procedures to preserve warranty eligibility.

Who is this for: The HS5167 front seal kit is aimed at marine technicians, boat owners comfortable with steering system service, and repair shops maintaining SeaStar hydraulic steering cylinders. If you already own a compatible SeaStar front-mount or pivot cylinder and need to stop leaks or refresh the front seal without replacing the entire unit, this kit supplies the exact seal glands and an alignment tool—but it does not include the wrench or extra internal components needed for full cylinder overhaul.
