⚙️ Key Features

• Approximate 80-100 mm clamping range
• Genuine wide-band heavy-duty clamp
• Suitable for large charge-air, air or SCR hose joints
• Correct factory clamping profile
• One clamp supplied; hose, seal and adjoining hardware are separate
• Engine type: Volvo Penta industrial diesel inlet/exhaust or aftertreatment system
• Quantity varies by assembly, most commonly one

🔌 Function

Applies uniform radial pressure to a large-diameter hose connection so the joint remains sealed against air, boost pressure or AUS/DEF fluid as applicable.

⚠️ Common Signs of Failure

• Boost or air leakage with whistling under load
• Oil mist or staining around a charge-air joint
• Hose movement or partial separation
• Corrosion, stripped screw or reduced clamping force
• DEF crystallisation where used in an SCR circuit

🛠️ 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
