Features: Used to replenish oil for the ship's steering system fluid. The clear hose allows visibility of oil flow, making the bleeding and filling process easier and more effective. Compatible with Seastar inboard and outboard hydraulic steering systems. Designed for refilling boat steering system fluid. High-quality brass fittings and PVC pipes provide reliable mechanical and physical performance, with excellent oxidation resistance, corrosion resistance, and durability. Helps maintain a sealed steering system during the bleeding process from end to end. Includes one bridge tube that screws into the reservoir and one bridge tube that connects to the bleed fitting. Specifications: Material: Polyurethane, Stainless Steel Color: Gold Tone, Black, Clear Black Tube: Length approximately 46cm / 18.11in Yellow Tube: Length approximately 45cm / 17.72in Product Dimensions: 20 x 14 x 14cm Package Weight: 150g Instructions: 1. Attach bottle to helm reservoir (do not puncture bottle; avoid letting bottle run empty). 2. Connect bridge tube to fittings on steering cylinder and loosen fittings. 3. Use the helm to pump fluid through the system by turning the wheel in one direction. Air bubbles will be pushed to the reservoir at the helm. 4. Manually move the outboard through full range of motion to release trapped air. 5. Position fittings upward while pumping fluid to allow air to escape from the cylinder. 6. Repeat steps 3–4 as needed until no air is visible in the bridge tube. 7. Tighten all fittings before removing the bridge tube. Package List: 1 x Bridge Tube 1 x Filler Hose with Screw Cap
