<h3>About Seastar Solutions</h3><p><strong>Seastar Solutions</strong> has been a cornerstone of the recreational marine industry for more than eight decades. <a href="/7554-seastar-solutions-seastar-solutions-hydraulic-steering-200917">Founded in 1943</a> and headquartered in Litchfield, Illinois, the company built its reputation under the Teleflex Marine name before rebranding to Seastar Solutions in February 2013. In 2017, it was acquired by the Dometic Group, further expanding its global reach while preserving the engineering heritage that boaters had come to rely on.</p><h3>A Legacy of Marine Innovation</h3><p>Seastar Solutions' story of innovation begins in 1962, when the company introduced the Big-T cable steering system — a revolutionary design that replaced the traditional rope-and-pulley mechanism with a helical cable, fundamentally changing how small boats are steered. In the decades that followed, the brand continued pushing the boundaries of marine engineering, introducing firsts like tilt steering for recreational boats, CANBUS steer-by-wire technology, and award-winning systems like the Optimus 360 Joystick Control System.</p><p>Today, Seastar Solutions products are sold worldwide under the SeaStar, BayStar, Sierra, Prime Line, and Proheat brands — each recognized for quality, reliability, and technical innovation. Whether you're outfitting a weekend fishing boat or a high-performance offshore vessel, Seastar Solutions offers a system engineered to match your needs.</p><h3>Hydraulic Steering: The Heart of the Lineup</h3><p>At the core of the Seastar Solutions catalog is its industry-leading line of <a href="/7554-seastar-solutions-seastar-solutions-hydraulic-steering-200917">hydraulic steering systems</a>. Covering outboard, inboard, and sterndrive applications, these systems — including the popular SeaStar Pro and BayStar series — are the benchmark for smooth, precise helm control. From hydraulic helm pumps and cylinders to hoses, fittings, and complete kits, Seastar Solutions provides everything needed to build or upgrade a fully capable steering system.</p><p>The brand's hydraulic systems are particularly valued for high-horsepower setups, where mechanical steering can become fatiguing and imprecise. By routing hydraulic fluid through a sealed system, these helms deliver consistent feedback and effortless control regardless of engine load — a key safety and comfort advantage for serious mariners.</p><h3>OEM Quality for Aftermarket Needs</h3><p>One of the most trusted aspects of the Seastar Solutions brand is its compatibility across generations of boats. Because the company carries forward the engineering legacy of Teleflex Marine, most legacy steering components integrate seamlessly with current Seastar parts. This makes Seastar Solutions a reliable choice not only for new builds but also for long-overdue upgrades or routine maintenance on existing vessels.</p><p>From control and throttle cables to installation hardware, cylinders, helms, and fluid maintenance kits, Seastar Solutions covers the full spectrum of marine steering and control needs — making it the go-to source for boaters who demand performance they can count on.</p>

Product Details

The Seastar Solutions HF5508 is a cylinder hose adapter kit designed for SeaStar II inboard hydraulic steering systems plumbed with copper tubing. This kit provides the necessary hardware to properly connect the steering cylinder to 3/8" O.D. copper tubing runs, ensuring a reliable, leak-free hydraulic connection at the cylinder end of the system.

Kit Contents:

  • Two (2) 18-inch flexible hydraulic hoses
  • Adapter fittings for cylinder connection
  • Compression nuts for 3/8" copper tubing interface

Key Features & Specifications:

  • Designed for single-cylinder installations on SeaStar inboard hydraulic steering systems
  • Compatible with SeaStar II helms with 4-1/4 or 5-1/2 turns lock-to-lock
  • Required when system is plumbed with 3/8" O.D. copper tubing (annealed copper refrigeration tubing with 0.032" wall thickness)
  • Copper tubing specification: 3/8" outside diameter, approximately 0.8mm wall thickness
  • Can also be used on outboard-powered boats equipped with SeaStar brass inboard cylinders
  • Use of this adapter hose kit is required for SeaStar brass cylinders when copper tubing is present

Copper tubing systems require the HF5508 specifically — do not substitute with the nylon tubing kit (HF5507). For optimal results, use annealed copper refrigeration tubing meeting the diameter and wall thickness specifications outlined in the SeaStar installation manual.
