21686488 Hose Clamp | Genuine Volvo Penta Part

🔧 Product Description

Formed or flexible hose manufactured for the original Volvo Penta fluid, air, vacuum or aftertreatment circuit. Correct length, bend, material and connection diameter prevent restriction, leakage and chafing.

• Volvo Penta TAD550GE

• Volvo Penta TAD751GE

• Engine Family: TAD

⚙️ Key Features

• Genuine Volvo Penta moulded hose or line
• Correct routing and clamp locations

🔌 Function

Transfers the designated fluid, air or vacuum signal through the original system route.

⚠️ Common Signs of Failure

• Hose creeping off its stub or weeping at the joint even with the clamp pulled tight
• Band cracked, rusted through or distorted so it no longer sits square on the hose
• Screw or worm thread stripped, seized or rounded so the clamp will not tighten
• Band cutting into the hose wall, leaving a deep groove or a split
• Clamp found loose at service with a witness mark showing it has slipped

🛠️ Service Notes

• Fit a new clamp whenever the hose is renewed, as a re-used band rarely pulls up to the same seal
• Tighten only until the joint seals: over-tightening cuts into the hose and causes the very leak the clamp is there to prevent
