The Koncentrik union is a four-piece assembly consisting of a threaded piece, tailpiece, union nut, and Teflon seal. The Teflon seal is seated in a precision-machined groove in the male cone shaped tailpiece. By using the chart below, many configurations can be made, by simply matching the threads on the threaded end to the threads on the corresponding nut.
