SOYLIN - Your Trusted Choice for Marine Hydraulic Maintenance SOYLIN is dedicated to providing reliable, high-performance marine and automotive tools. We understand that fixing a leaking front mount hydraulic steering cylinder shouldn't require hunting down multiple scattered parts, nor should you have to deal with fragile tools that snap at the worst possible time. That is why we engineered a comprehensive all-in-one solution for your vessel. The Complete Repair & Bleed Solution Whether you are dealing with a weeping cylinder, a seized support bracket, or spongy helm control caused by trapped air, the SOYLIN Complete Hydraulic Steering Repair & Bleed Kit provides everything you need. Designed for outboard, inboard, and sterndrive boat steering systems, this professional combo set allows you to flush steering fluids, replace worn seals, and extract stubborn brackets safely and efficiently. Why Choose the SOYLIN Upgrade Kit? Say No to Broken Tools: We listened to the frustrations of boat owners. Standard aluminum pin wrenches often bend or break under pressure. Our kit features a significantly upgraded Adjustable Pin Wrench forged from high-strength alloy steel, paired with an ergonomic red handle. It delivers superior torque and secure leverage to grip gland holes without slipping or deforming. Marine-Grade Durability: The support bracket puller is crafted from high-hardness 4140 impact-resistant steel with a black oxide finish, offering excellent defense against saltwater rust. The HS5157 cylinder seals utilize premium aircraft-grade aluminum and wear-resistant rubber O-rings to stop oil leaks effectively. Leak-Free Fluid Flush: The included marine power steering fluid bleed kit is built with precision brass fittings and high-flex transparent PVC tubing. The upgraded threaded caps ensure a tight, mess-free connection to your fluid bottle, allowing a seamless, one-person air bleeding process to restore highly responsive steering. Extensive Compatibility Engineered to be a reliable replacement part for SeaStar, BayStar, and Uflex hydraulic steering setups.
