Information
O-Ring, 19.6 X 3.53N.
The O-Ring 19.6 x 3.53N is a genuine Porsche OEM sealing ring designed to create a tight, leak-free seal between coolant pipe connections and related engine cooling system components. Manufactured to precise dimensions, this O-ring fits into the mating groove of the pipe joint to prevent coolant loss and maintain correct system pressure. It is an essential replacement seal used on various Porsche coolant and inlet pipe applications.

What This Product Does:
- Seals coolant pipe joints to prevent coolant leaks between connected pipes and fittings.
- Maintains correct cooling system pressure, which is essential for efficient engine temperature control.
- Creates a tight seal between metal components by compressing inside a groove when the pipe connection is tightened.
- Coolant may seep or drip from the joint where the O-ring seals the connection.
- A worn O-ring can cause slow coolant loss, leading to frequent topping up.
- Loss of coolant or system pressure can reduce cooling efficiency and contribute to overheating.
- A leaking O-ring often produces a noticeable coolant smell near the engine bay.
- The O-ring may show cracking, flattening (loss of shape), swelling, hardening or brittleness
- Modern Porsche models may trigger low coolant warnings if leakage occurs.
- Prevents coolant leaks at pipe connections, avoiding coolant loss and contamination.
- Maintains correct system pressure, which is essential for efficient engine cooling performance.
- Helps prevent engine overheating, since even a small leak can lead to low coolant levels and temperature rise.
- Protects surrounding components, as leaking coolant can damage hoses, sensors, connectors, and nearby engine parts.
- Ensures reliable long-term sealing, since old O-rings harden and flatten over time due to heat and pressure cycles.
