T25,G1 Water Hose Connecting Pipe

This radiator hose connecting pipe is designed to join cooling system hoses securely within the engine cooling circuit. Manufactured as a direct replacement for the original connector, it is commonly used in Volkswagen cooling systems where a straight inline hose connection is required.

With a 12.5mm internal diameter, 16mm outer diameter and 62mm overall length, this connector provides a reliable and leak-free join between coolant hoses. It is suitable for a wide range of classic Volkswagen applications including Golf Mk1, Jetta Mk1, Scirocco Mk1 and T3/T25 Transporter models.

A worn or damaged cooling hose connector can lead to coolant leaks, poor cooling system performance and overheating issues. Replacing ageing plastic or corroded connectors during cooling system maintenance helps improve long-term reliability and prevent unexpected failures.
