I have a 1/2 Polybutylene gray pipe that I need to terminate. I've tried Lowes and Home Depot but haven't found anything. Doing a little research turned up sharkbite but I've read I need special sharkbite to connect to the Polybutylene and even then, it's not a termination fitting. What are my options. tearing all the Polybutylene is not an option for me right now. I did find some 1/2 refrigerator copper line that I capped and tried, it fits pretty tightly but even when using a band clamp there is still a small drip. Was wondering what others have done.
