Claim 0:
1. An end termination assembly for a pipe liner, the end termination assembly comprising:
a liner fitting having an axis, the liner fitting comprising a pipe coupling configured to couple to a host pipe system and a nipple configured to be inserted into an end portion of the pipe liner, the nipple extending away from the pipe coupling in a first axial direction, the nipple having a first end and a second end spaced apart from the first end in a second axial direction opposite the first axial direction, the nipple comprising an annular outer wall having an outer dimension and a length extending along the axis from the first end of the nipple to the second end of the nipple;
a clamping collar having a first end and a second end spaced apart from the first end of the clamping collar in the second axial direction, the clamping collar comprising an annular inner wall, the annular inner wall having an inner dimension and a length extending along the axis from the first end of the clamping collar to the second end of the clamping collar, the clamping collar being configured to be disposed about the nipple to clamp an end of the pipe liner between the annular inner wall and the annular outer wall of the nipple to fluidly couple the end termination assembly to the pipe liner, the length of the outer annular wall of the nipple being greater than the length of the annular inner wall of the clamping collar;
at least one of the annular inner wall of the clamping collar and the annular outer wall of the nipple tapering radially inward as it extends lengthwise in the first axial direction such that the respective one of the inner dimension and the outer dimension gradually decreases from the second end to toward the first end of the respective one of the clamping collar and the nipple;
the clamping collar being operatively connectable to the nipple for nonrotational movement with respect to the nipple along the axis in the second axial direction for clamping and sealing the pipe liner onto the nipple.
