22349398 Bleeder Nipple | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta bleeder nipple used at a designated service point to release trapped air and control fluid discharge during filling, bleeding or maintenance. The precision seat and thread are important for achieving a leak-free closure after the system has been vented.

🚤 Compatibility

Typically suits:

• Volvo Penta IPS40-A
• Volvo Penta D13C8-B MP
• Volvo Penta D13C4-B MP

• Engine Family: IPS, D

⚙️ Key Features

• OEM bleed-point fitting
• Controlled venting during filling and service
• Precision sealing seat and threaded connection
• Designed for repeated maintenance access
• Replace if seized, rounded, damaged or leaking
• Engine type: Volvo Penta diesel engine service/bleed circuit

🔌 Function

Allows trapped air to be expelled from the assigned circuit during filling or servicing. Once bleeding is complete, the nipple seals the service port to maintain system pressure and prevent fluid loss or air entry.

⚠️ Common Signs of Failure

• Persistent seepage around the nipple after tightening
• Rounded or damaged wrench flats
• Blocked bleed passage or inability to vent trapped air
• Seized or corroded threads
• Damaged sealing tip or seat
• Recurring air lock after service when the bleed point will not seal

🛠️ Service Notes

• Fit a new nipple rather than reusing one with rounded flats or a damaged sealing tip — these will not achieve a leak-free closure
• Do not overtighten when closing after bleeding; this can damage the sealing seat rather than improve the seal
• Confirm the bleed sequence for the specific engine before use, as bleed order varies by circuit

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
