🔌 Function

A hose clamp compresses a hose end onto its fitting to maintain a sealed joint against internal pressure and engine vibration. It prevents the hose from slipping off or weeping at the connection.

⚠️ Common Signs of Failure

• Coolant, oil, air or fuel weeping or spraying from the hose joint
• Corroded, pitted or seized clamp band or tightening screw
• Clamp will no longer hold torque and loosens repeatedly after tightening
• Hose creeping or blowing off the spigot under pressure
• Cracked or distorted band that has cut into the hose surface

🛠️ Service Notes

• Match the clamp to the hose outside diameter so the band closes well within its working range rather than at the very end of its travel
• Position it over the spigot behind the bead or barb, with the screw where a driver or spanner can still reach it once everything is refitted
• Tighten to seal, not to crush — an over-tightened worm-drive clamp cuts into soft hose and starts the leak you were trying to stop
• Renew clamps when a hose is changed rather than reusing them, and keep band, housing and screw all marine-grade stainless so the clamp does not corrode against itself
• Where two clamps are fitted to one connection, stagger the screw heads and recheck both after the first running period
