This kit includes a pin wrench, a seal gland assembly guide tool, two seal glands, and four sizes of black rings, with broad compatibility across many Sea Star models.

The HS5167 kit contains two seal glands and a seal gland assembly guide tool and is compatible with a wide range of front-mount models. It’s a reliable OEM-style option for standard seal replacements. Best for the user who wants a clean, simple install without extra specialty tools.

NBPLUS emphasizes high-quality seals, and the HP6032 kit covers multiple helm models like HH5271, HH5272, HH5273, and more. Use this when you need a versatile kit for various helm configurations. A limitation is the kit’s breadth; ensure the specific model is listed in its compatibility notes before purchasing.
SeaStar HS5157 With Wrench

The HS5157 kit includes two seal glands, a pin wrench, and a gland assembly guide tool, fitting models like HC5340–HC6755. It provides a balanced option for professionals and serious DIYers who want a complete kit with the right tools. Caution: verify exact cylinder compatibility to avoid mismatches.
Buying Guide
- Compatibility matters. Check your cylinder model numbers (HC5340–HC6755 family) and mounting type (front-mount vs pivot). Choose a kit explicitly listed as compatible to prevent leaks or fit issues.
- Tools included or required. Some kits come with a pin wrench and guide tools; others require you to have basic tools separately. If you’re new to hydraulic steering maintenance, pick a kit with included tools.
- What the kit contains. Look for seal glands, O-rings, gasket rings, and any necessary hardware. A complete kit saves time and reduces the likelihood of missing components during reassembly.
- Durability and material quality. Aircraft-grade aluminum components and hardened steel pullers offer better torque resistance and corrosion protection in marine environments.
- Ease of installation. Kits with guided assembly tools or step-by-step instructions help ensure a proper seal and alignment, reducing installation errors.
- Warranty and replacement parts. OEM or OEM-style kits typically provide reliable seals and better long-term performance; consider sellers offering clear return policies.
