A connector apparatus is described for joining two pipe sections containing a hard-to-handle fluid, the apparatus comprising: a first pipe section having an interior passageway and composed of a non-fluid-resistant material; a first substantially rigid, pipe end segment composed of a first fluid-resistant material and attached to one of said two pipe sections; a brittle fluid-conducting liner composed of a second fluid resistant material other than said first fluid-resistant material and substantially covering said interior passageway, the liner attached to the interior passageway and sealably bonded to the first segment; a second pipe section for joining to said first pipe section; and means for joining the pipe sections, wherein the liner and the liner bonding prevent said fluid from contacting said non-fluid-resistant material when said pipe sections are joined in the absence of a deformable material contacting said liner, wherein: the first segment also comprises a primary sealing surface proximate to one segment end bonded to said liner and a secondary sealing surface; the second pipe section also comprises a second pipe end segment composed of a corrosion resistant material and at least one mating sealing surface spaced apart from the secondary sealing surface when the pipe sections are joined; the means for joining comprises a threaded surface on said first segment and a mating threaded surface on said second segment; and the apparatus also comprises a deformable secondary sealing element which is also capable of sealing when sandwiched between the secondary sealing surface and a mating sealing surface.
