21905286 Pipe | Genuine Volvo Penta Part

🔧 Product Description

Rigid pipe used in the TAD870-TAD873VE inlet/exhaust system to carry pressure to or from the associated sensor connection. Its internal volume and routing support accurate pressure measurement while avoiding heat and vibration damage.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD870-73VE

• Engine Family: TAD

⚙️ Key Features

• Correct internal diameter for the assigned flow
• Designed for original seals, clamps and supports
• Rigid construction limits vibration movement
• Exact engine configuration must be confirmed

🔌 Function

Transfers pressure from the monitored air/exhaust passage to the sensor while isolating it from direct flow and excessive vibration.

⚠️ Common Signs of Failure

• Blocked pipe causing implausible pressure readings
• Cracking or soot leakage
• Sensor fault or engine derate
• Loose unions
• Heat or vibration fatigue

🛠️ Service Notes

• Offer the pipe up and check it reaches both connections freely before you tighten anything — a rigid pipe pulled into place is a pipe left under permanent strain, and strained pipes crack at the fittings in service
• Renew the sealing washers, O-rings or union seals that go with the pipe rather than reusing the old ones, and make sure the seats, faces and threads are clean
• Keep the ends capped while you work and blow or flush a pipe through before fitting; anything left inside goes straight into the oil, fuel or coolant system
• Tighten unions and banjo bolts evenly to the figures in the workshop manual for your engine — overtightening distorts the seat and starts the leak you were trying to cure
• Refit every clip and support bracket in its original place and keep the pipe clear of hot or moving parts so it cannot chafe or be shaken to failure
