Information
O ring seal water pipe, 39.3 x 3.53 mm
This original Porsche sealing ring is used in the engine cooling system, helping seal the coolant pipe connection and prevent coolant leaks.
Sold individually,
Fits:
Porsche 987.1 Boxster 2005 - 2008
Porsche 987.2 Boxster 2009 - 2012
Porsche 987C.1 Cayman 2005 - 2008
Porsche 987C.2 Cayman 2009 - 2012
Diagram ref no 39
This O-ring is used on selected Porsche 987 Boxster and Cayman cooling system pipework.
What This Part Does / Functions
• Seals the water pipe / coolant pipe connection
• Helps prevent coolant leaks
• Maintains cooling system pressure
• Supports correct coolant flow through the engine and radiator circuit
• Helps prevent air entering the cooling system
• Replaces a hardened, flattened, cut or leaking original O-ring
• Provides correct OE Porsche size, material and fitment
• Supports correct reassembly after coolant pipe or hose service.
Why Replace This Part?
Coolant O-rings are exposed to heat cycles, coolant pressure, vibration and age-related rubber deterioration. Over time, the seal can harden, flatten, crack or lose elasticity. A worn O-ring may allow coolant seepage from the pipe connection, leading to coolant loss, pressure loss or low coolant warnings. Replacing it with a Genuine Porsche OE water pipe O-ring helps restore the correct seal and supports reliable cooling system operation.
Common Symptoms of a Failed Water Pipe O-Ring
• Coolant leak around the water pipe connection
• Dried coolant residue near the pipe joint
• Low coolant warning
• Coolant smell from the engine bay
• Cooling system pressure loss
• Air entering the cooling system
• O-ring found flattened, cut or hardened during inspection
• Coolant seepage after previous pipe or hose work.
When to Replace This Part
• Whenever the water pipe or coolant pipe is removed
• During coolant hose or pipe replacement
• If coolant is leaking from the pipe connection
• If the O-ring is hardened, flattened, cracked or damaged
• During cooling system overhaul or repair
• When replacing related coolant pipes, hoses or housings
• After separating the water pipe connection
• Whenever Porsche workshop procedure recommends replacing the seal after removal.
Where It Fits on the Car
This O-ring fits in the engine cooling system water pipe / coolant pipe connection. It is commonly shown in Porsche cooling diagrams in the feed and return water hose / coolant hose centre section area. Correct installation is important. The sealing surface should be clean, and the O-ring should be fitted without twisting, pinching or damage.
