🔌 Function

Clamps a breather hose onto its stub so the crankcase-ventilation joint stays sealed under vibration.

⚠️ Common Signs of Failure

• Oil mist escaping from under a hose end
• Hose found to have crept off its stub
• Clamp found corroded, sprung or the screw seized
• Band having cut into the hose wall from over-tightening
• Hose end hardened where the clamp has been sitting

🛠️ 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
