I'm fitting a black designer radiator onto a black wallpapered wall. Due to gaps in the radiator, you can see the wall through the radiator. For a neat finish, I'll be using black plastic pipes, however I would also like to use a black outlet pipe for the black pipes onto my dry wall. Does anyone make these in black? I know you can get the ones below in white, but they've told me they don't make them in black.
