In a water flow system, a non-metallic liner 50 is placed within at least a portion of a passage 48 of a supporting metallic end body 38 to preclude contact between any water flowing through the system and the passage of the end body. The liner 50 includes a flared section 60 at a first end 54 thereof which engages a bevelled surface 49 of the end body 38 and is held there in sealing fashion by a cone washer 82 and a nut 84 threadedly coupled to the end body. At a location near a second end 56 of the liner 50, the liner is formed with a first stepped shoulder 62 which facilitates location of the liner within the passage 48 of the end body 38 at the second end of the liner. A second stepped shoulder 64 is formed on the liner 50 which provides a location for an O-ring 72 which engages an adjacent portion of the passage 48 of the end body to form a seal thereby. With seals formed at the first and second ends 54 and 56 of the liner 50, any water passing through the liner will not contact the passage 48 of the end body 38.

[ What is claimed is:] [1.] An isolated conduit system, which comprises:a rigid metallic support having a passage with an interior wall formed therethrough;the passage of the support formed with a first end opening and a second end opening spaced therefrom, the spacing of which defines a prescribed distance of the length of the passage;a liner, composed of a non-metallic material, is formed with a passage through the liner and has an interior wall and a first end opening and a second end opening spaced from the first end opening;the liner being formed with a generally cylindrical intermediate section, a first end section, and an integrally-joined outwardly flared second end section spaced from the first end section;the liner being located within the passage of the metallic support with the first end openings of the support and the liner being juxtaposed and the second end openings of the support and the liner being juxtaposed;the liner being of sufficient length and shape, to isolate the interior wall of the metallic support from the interior wall of the liner; andmeans provided adjacent the juxtaposed first end openings and the juxtaposed second end openings for isolating adjacent portions of the interior walls of the support passage from adjacent portions of the interior walls of the liner passage.
