20429999 Grommet | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta rubber grommet used at a cable or wiring-harness pass-through. It cushions the harness and seals the opening against abrasion, water and dust.

⚙️ Key Features

• Original keyed Volvo Penta harness component
• Protects and locates electrical terminals or cable insulation
• Used in sealed engine wiring assemblies
• Must match the original connector family and pin arrangement
• Inspect seals and terminals during replacement
• Engine type: Volvo Penta electronic diesel electrical systems

🔌 Function

Supports, insulates, retains or seals the engine wiring harness at the assigned connector or pass-through position.

⚠️ Common Signs of Failure

• Intermittent electrical or sensor fault
• Water or corrosion inside the connector
• Broken locking or retaining feature
• Harness abrasion at the opening

🛠️ Service Notes

• Renew the grommet whenever the cable, pipe or shaft it seals is disturbed; old rubber takes a set and will not seal or grip again
• Check that the hole or bore is clean, free of burrs and undamaged — a sharp edge will cut a new grommet
• Ease the grommet in with clean water or the correct rubber lubricant, not with oil, grease or fuel, unless the assembly is oil-wetted by design
• Make sure the grommet is fully home all round with the cable or pipe centred in it, so nothing is left bearing on the edge of the hole
