<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 HF5518 is a vertical bleeder tee fitting designed for use with older-style SeaStar manual hydraulic marine steering systems. Sold as a pack of two, these fittings are an essential component for bleeding and maintaining hydraulic steering cylinders to ensure reliable, responsive helm performance on the water.

These are 3/8" compression fittings utilizing a 9/16"-24 extra fine thread, compatible with all older-style SeaStar manual hydraulic steering systems. The fittings are constructed from corrosion-resistant stainless steel, providing long-lasting durability in the harsh marine environment.

Key Features:

  • Vertical bleeder tee orientation for convenient system bleeding
  • 3/8" tube compression fitting with 9/16"-24 extra fine thread
  • Corrosion-resistant stainless steel construction
  • Sold as a pack of two fittings
  • Compatible with all older-style SeaStar manual hydraulic steering systems
  • Not for use with newer SeaStar cylinders with part numbers ending in "-3" — those require ORB (O-Ring Boss) fittings sold separately

The HF5518 is the correct bleeder tee for legacy SeaStar hydraulic steering installations. If your cylinder or helm part number ends in "-3" or "-4", refer to the HF6002 ORB-style bleeder tee instead. All SeaStar manual hydraulic steering systems use the same style of compression fittings across applications, making the HF5518 a universal solution for older system maintenance and repair.
