Full model list at the end of this description.

⚙️ Key Features

• OEM sealing profile for the specified TAD16 flange joint
• Resists boost pressure, exhaust heat and engine vibration as required by position
• Works with the original flange and V-band clamp arrangement
• Should be renewed whenever the sealed joint is dismantled
• Prevents gas leakage and associated loss of engine performance
• Engine type: 16.1 L six-cylinder turbocharged/aftercooled diesel

🔌 Function

Forms a pressure-tight and temperature-resistant seal between the designated pipe and flange surfaces.

⚠️ Common Signs of Failure

• Soot, oil mist or gas staining around the joint
• Whistling, hissing or exhaust ticking under load
• Reduced boost pressure or loss of engine power
• Ring crushing, cracking, erosion or heat damage
• Leakage returning after reuse of the old sealing ring

🛠️ Service Notes

• Always fit a new sealing ring rather than reusing the old one — a ring that has been compressed once has taken a set and will not seal reliably a second time
• Clean the groove or seat and check it for scoring, corrosion and old sealant before fitting; a mark across the sealing face will leak however good the ring is
• Ease the ring into place without stretching, twisting or dragging it over sharp edges or threads, and check it is seated squarely all the way round before closing the joint
• Do not add sealant or jointing compound unless the workshop manual for your engine calls for it, and tighten the joint or union to the figure given in that manual
• Check the joint for weeping once the engine has been run up to temperature and allowed to cool, as many sealing rings only show a leak after a heat cycle
