🔌 Function

The clamp holds a hose, pipe or cable securely against its fitting or mounting point, maintaining a sealed joint and preventing movement or chafing. Correct clamping tension keeps fluid connections leak-free under engine vibration and thermal cycling.

⚠️ Common Signs of Failure

• Corrosion, pitting or rust staining on the clamp band or screw
• Fluid weeping or seepage at the clamped joint
• Loss of clamping tension so the hose or line can be twisted or pulled by hand
• Cracked, distorted or fractured clamp band
• Seized or stripped tightening screw that cannot be retorqued

🛠️ Service Notes

• Fit a new clamp rather than reusing one that has been distorted, stretched or corroded; a band that has been drawn down onto a hose once rarely grips evenly again
• Use the correct size and type for the joint — an over-large clamp will not draw down evenly and can cut into a soft hose instead of gripping it
• Position the clamp fully over the spigot or pipe bead, clear of the hose end, and tighten only until the joint is secure; over-tightening crushes hoses, pipes and cable insulation
• Set the screw or head where you can reach it for later checks, and make sure the clamp is not resting anywhere it will chafe a neighbouring hose or harness
• Re-check tightness after the first run up to temperature, as hoses relax and settle once they have been heated
