ABSTRACT:
A multi-piece, pipe joint seal has a slidable interface between seal pieces. The slidable interface allows for slippage between pieces during pipe joint assembly and disassembly, minimizing rotational and other stresses on the seal pieces and pipe sealing surfaces which may damage or endanger the deformable seal. The slidable interface seal is especially useful for joining brittle-lined pipe sections handling harsh fluids.
