Heater Pipe O-Ring, Victor-Reinz - E46, E39, E60, E83, E53, Z3, Z4

Coolant hoses are sealed with a rubber o-ring inside the connector. Any time the hose is removed or disconnected the o-ring should be replaced. The o-ring can shrink with heat and time or become damaged. It's common to have leaks when re-using the hose and o-ring.

Instead of replacing the entire hose we offer the correct size replacement o-ring. This o-ring is used for the heater pipes on the side of the engine block and the return hose to the expansion tank.

This part is manufactured by an aftermarket supplier of European auto parts, including many seals and gaskets. While not carrying OEM status, this part follows the design of the original very closely and uses similar materials. An aftermarket part may even have the same TUV approval as its OEM counterpart. The brand may even be OEM to another manufacturer besides BMW. This aftermarket brand has a two year warranty - the same as Genuine BMW and OEM brands.
