• Confirmed with Stage 1 / Tier 1 induction components

• Must match the hose or elbow outside diameter
• Inspect the hose beneath the clamp for cuts or deformation
• Engine type: Volvo Penta 5- and 7-litre turbocharged industrial diesel
• 80mm (Volvo assembly listing)
• Quantity varies by assembly, most commonly one

🔌 Function

Secures the air-cleaner, elbow or manifold connection so filtered air cannot leak or draw in dust.

⚠️ Common Signs of Failure

• Dust tracks downstream of the filter
• Intake whistle
• Loose hose or elbow
• Clamp corrosion or distortion
• Hose split beneath the clamp

🛠️ 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
