1. A method of connecting oil or gas pipes, comprising:
positioning a pair of pipe ends of oil or gas pipes proximate corresponding one of a pipe connector first end and a pipe connector second end, wherein said first of said pair of pipe ends comprises a first material and said second of said pair of pipe ends comprises a second material, said first material different material than said second material, said pipe connector including:
a tubular conduit formed of one plastic material having a length disposed between said pipe connector first end and a pipe connector second end, said pipe connector having a pipe connector wall disposed between a pipe connector external surface and a pipe connector internal surface, said pipe connector internal surface defining an interior passage open at said pipe connector first end and said pipe connector second end to correspondingly receive said pair of pipe ends, wherein said pipe connector first end including:
a first internal annular seal groove circumferentially disposed in said pipe connector internal surface of said tubular conduit proximate said pipe connector first end;
a first seal element disposed in said first internal annular seal groove, wherein a portion of said first seal element extends outward of said pipe connector internal surface into said interior passage;
inserting said first of said pair of pipe ends of said first material into said pipe connector first end;
sealably engaging said first of said pair of pipe ends with said first seal element;
inserting said second of said pair of pipe ends of said second material into said pipe connector second end; and
sealably engaging said second of said pair of pipe ends with said pipe connector internal surface of said pipe connector second end, said internal surface of said pipe connector second end having a constant cross-section diameter in axial direction between said pipe connector second end and an internal annular member circumferentially medially disposed on said pipe connector internal surface of said tubular conduit.
