3840433 Sealing Plug | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta sealing plug for the connection in the HIU when a reverse gear is used, from the Cables and Fuses group, weighing 4.5 grams and listed for 296 applications across IPS, D, V, TAD, DPH and DPI families. It supersedes part number 3807515, which was catalogued earlier simply as a plug. Sealing plug 3840434 is the heavier alternative at 6.8 grams and carries no listed applications, so use the HIU reverse gear note to pick this one.

⚙️ Key Features

• For the connection in the HIU when reverse gear is used
• 4.5 grams
• 296 applications across six families
• Supersedes 3807515, previously catalogued as a plug
• Lighter than sealing plug 3840434

🔌 Function

Blanks off and seals the unused HIU connection so water and dirt cannot enter it.

⚠️ Common Signs of Failure

• Moisture, salt or green corrosion found inside the HIU connection
• Intermittent electrical faults traced to a wet connector
• Plug loose, split or missing altogether
• Seal perished so the plug no longer grips

🛠️ Service Notes

• Only the unused connection gets blanked - confirm the reverse gear installation before plugging anything
• Check the connection is clean and dry before fitting, as a plug will seal moisture in as readily as out
• Sealing plug 3840434 is a different, heavier part and is not a substitute
