🔧 Product Description

Genuine Volvo Penta hose clamp weighing 0.025 kg and listed for 14 applications across the D, TWD and TAD engine series. It supersedes part number 943469, which the earlier records carried simply as a clamp, so an older parts list may not describe it as a hose clamp at all.

🔌 Function

Draws tight around the hose to squeeze it onto its spigot, holding the joint sealed against pressure and vibration.

⚠️ Common Signs of Failure

• Hose creeping off its spigot, or a weep at the joint
• Band corroded, cracked or the screw thread stripped
• Clamp will not tighten further although the joint still leaks
• Band cutting into or biting through the hose wall

🛠️ Service Notes

• Renew the clamp with the hose rather than reusing a band that has already been pulled up hard
• Check the spigot barbs and the hose end for damage before refitting
