Questions

  1. does it have ceramic inside it?

    The piece I have is for a hot pressure washer. It has a ceramic internal piece that I believe acts as a reducer as well as an insulator so the heat is not conducted. Does this have this as well? If not do you have one that does?

    1 answer

    1. This coupler does not have ceramic in it. It features a unique red insulated sleeve to help protect your fingers from excessive heat when switching out nozzles. Northern Tool does not currently offer a coupler that has ceramic in it.
