    Copper or brass olive for chrome pipe

    Hello all. I hope you are having a nice weekend. I’m adding a new rad to my bathroom and will be using chrome pipe. It’s my understanding that compression fittings can be used straight on the chrome without filing of chrome finish. What olive is best to use. Copper or brass? Many thanks.
