🔧 Product Description

This genuine Volvo Penta hose clamp is a high-load charge-air hose clamp used in the charge-air/intercooler hose connection. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. Clamp range: approximately 84-96 mm. In service, it secures the charge-air hose to its pipe or cooler connection under boost pressure.

🔌 Function

A hose clamp compresses the end of a flexible hose against its mating spigot or pipe to form a leak-free mechanical joint. It maintains that clamping load throughout engine heat cycles and vibration to prevent the hose from loosening or blowing off.

⚠️ Common Signs of Failure

• Coolant, fuel, oil or air leaking at the hose-to-spigot joint
• Visible corrosion, pitting or rust on the clamp band or screw housing
• Stripped, seized or rounded tightening screw that will not hold torque
• Hose slipping, creeping or blowing off the connection under pressure
• Cracked or distorted clamp band that no longer applies even clamping force

🛠️ 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
