🔌 Function

The pipe carries hydraulic fluid between elements of the steering system so that helm input is transferred to the drive or steering cylinder. It maintains a sealed, pressure-tight path within the steering circuit.

⚠️ Common Signs of Failure

• Visible hydraulic fluid weeping or dripping at the pipe body or its end fittings
• External corrosion, pitting or flaking that thins the pipe wall
• Cracks or splits caused by vibration fatigue or chafing against adjacent components
• Soft, spongy or heavy steering feel from pressure loss or air drawn into the circuit
• Bent, kinked or deformed sections restricting fluid flow

🛠️ Service Notes

• Offer the pipe up and check it reaches both connections freely before you tighten anything — a rigid pipe pulled into place is a pipe left under permanent strain, and strained pipes crack at the fittings in service
• Renew the sealing washers, O-rings or union seals that go with the pipe rather than reusing the old ones, and make sure the seats, faces and threads are clean
• Keep the ends capped while you work and blow or flush a pipe through before fitting; anything left inside goes straight into the oil, fuel or coolant system
• Tighten unions and banjo bolts evenly to the figures in the workshop manual for your engine — overtightening distorts the seat and starts the leak you were trying to cure
• Refit every clip and support bracket in its original place and keep the pipe clear of hot or moving parts so it cannot chafe or be shaken to failure
