20551429 Fitting | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta fitting is an OEM service component used in the Cooling-System Pipe Fitting. It is manufactured to the original Volvo Penta dimensional, material and interface requirements for the documented Volvo Penta 5-litre TAD5 generator diesel application. Technical identification: Threaded fitting joining the specified pipe/hose to its housing. In service, it routes the specified fluid or pressure signal between matched components without leakage, restriction, vibration damage or incorrect connection geometry. Selection must be confirmed by OEM part number 20551429, the exact model/product number, serial number and installed assembly configuration.

🔌 Function

Routes the specified fluid or pressure signal between matched components without leakage, restriction, vibration damage or incorrect connection geometry. Install without twist or preload, renew the specified seals/clamps, preserve the original routing and pressure- or leak-test the circuit after assembly.

⚠️ Common Signs of Failure

• Visible fluid leakage, dampness or staining along the line or connection
• Cracking, chafing, corrosion or impact damage
• Restricted flow caused by deposits, deformation or internal collapse
• Vibration fretting or failed support at clamps and mounting points

🛠️ Service Notes

• Identify the thread form and sealing arrangement before you start — a tapered thread seals on the thread itself, a parallel one seals on a washer, O-ring or cone face, and the two are made up in quite different ways
• Renew the sealing washer or O-ring, start the fitting by hand, and tighten to the figure in the workshop manual; a fitting drawn up hard to cure a leak usually splits the boss it is screwed into
• Use sealant or thread tape only where the manual specifies it, keep it off the leading threads and off any sealing face, and never allow any of it inside the passage
• Hold the fitting with a spanner on its hexagon while the pipe or hose union is tightened, so the torque is not passed into the casting behind it
• Check for weeping with the system at working pressure and temperature, not only cold
