🔌 Function

Holds a breather hose or return line at a fixed point so vibration cannot chafe it or work its connections loose.

⚠️ Common Signs of Failure

• Hose rubbed shiny or worn through where it passes the clamp
• Oil mist escaping from a chafed breather hose
• Clamp found cracked, sprung open or corroded
• Rubber liner perished so the hose sits on bare metal
• Fixing hole elongated where the clamp has been moving

🛠️ 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
