Diagram ref no 17
The joining socket forms a secure connection point within the coolant circuit, allowing coolant to pass correctly between the water pump housing and connected fittings or pipe sections. It helps maintain coolant flow, supports engine temperature control, and prevents coolant leaks around the water pump housing area.
Functions
• Connects the water pump housing to coolant fittings or pipework
• Helps maintain correct coolant flow through the engine cooling system
• Provides a secure joining point between cooling system components
• Helps prevent coolant leaks at the water pump housing connection
• Supports reliable engine temperature regulation
• Restores correct fitment when replacing or servicing coolant pipes
• OE Match design for direct replacement and accurate installation
The water pump housing joining socket is exposed to constant heat cycles, coolant pressure, vibration, and age-related wear. Over time, the connector can corrode, crack, seize, or fail to seal correctly, leading to coolant leaks or poor cooling system reliability. Replacing it during water pump or coolant pipe service helps ensure a tight, secure connection and protects the engine from coolant loss or overheating.
When to Replace
• Coolant is leaking around the water pump housing or pipe connection
• The joining socket is cracked, corroded, damaged, or seized
• The cooling system has been dismantled for water pump or pipework repairs
• Coolant fittings or pipe bends are being replaced
• The original connector no longer seals correctly
• There are signs of coolant residue or staining near the connection
• As preventative maintenance during major cooling system work
This connector fits into the engine's cooling system, near the water pump housing. It connects the cooling system hoses or fittings to the water pump housing and can be used at several points in the cooling system, depending on the engine model and design. Some refer to it as a water pipe joining socket, water pump housing connector, or coolant pipe adapter.

This OE Match coolant pipe O-ring seal is a replacement sealing ring used at the water pump housing and coolant pipe connection on Porsche 996 and 997 models. It is designed to match the original seal dimensions and provide a secure, leak-resistant fit within the engine cooling system.
Sold individually, 4 required per vehicle
Fits:
Porsche 996 Turbo 2001 - 2005
Porsche 996 GT3 2000 - 2005
Porsche 997 Turbo / GT2 2007 - 2009
Porsche 997 GT2 RS 2011
Porsche 997 GT3 2007 - 2011
Diagram ref no 18
The O-ring creates a tight seal between the coolant pipe/joining socket and the water pump housing. It prevents coolant from escaping at the connection point and helps maintain the correct pressure and flow within the cooling system.
Functions:
• Seals the coolant pipe connection at the water pump housing
• Helps prevent coolant leaks from the joint
• Maintains cooling system pressure
• Supports correct coolant flow around the engine
• Helps protect the engine from coolant loss and overheating
• Provides an OE Match replacement for the original sealing ring
• Suitable for use during water pump, coolant pipe, or joining socket service
Coolant O-rings are exposed to heat, pressure, coolant additives, and repeated engine temperature cycles. Over time, the seal can harden, flatten, crack, swell, or lose elasticity, which may cause coolant leaks around the water pump housing. Replacing the O-ring helps restore a reliable seal and is recommended whenever the connected coolant pipe or joining socket is removed.
When to Replace
• Coolant is leaking from the water pump housing connection
• The O-ring is flattened, brittle, cracked, swollen, or damaged
• The coolant pipe, joining socket, or water pump housing has been removed
• There is visible coolant residue or staining around the joint
• The cooling system is being repaired or pressure-tested
• The original seal no longer seats correctly
• As preventative maintenance during water pump or coolant pipe replacement
Where it fits on the car
This O-ring fits in the engine cooling system at the water pump housing area. On the diagram, it is shown as item number 18, sealing the coolant pipe/joining socket connection. It works with the adjoining coolant pipe fittings and sealing components to keep the water pump housing connection leak-free.
