The end of the bypass pipe (between thermostat and water pump) on my d15 Honda Civic ek3 has rotted off and water is flowing out pass the O ring. What is the part number for its replacement as I am seeing more than one?

Thanks for the quick response, much appreciated. I am in Jamaica and I doubt anyone has this part new, so I am looking to buy it used. Is there a part number for the seals/O rings as well?
