Abstract:
In an end fitting/pipe coupling in which to receive an open end of flexible pipe to be joined including a central passage in which a flexible pipe end is to be received, a seal within the fitting/pipe coupling operatively effective to seal against leakage while resisting pullout forces applied externally to the received pipe end comprising:an annular member of predetermined width supported within the fitting/pipe coupling and defining an internal diameter located to contiguously surround the periphery of a received pipe end; andsaid member being formed substantially at least about said internal diameter of spaced apart parallel discs of elastometric composition inclined at an obtuse angle relative to the axis of said internal diameter and molded about metal shims intervening between each pair of said discs from at said plane so as to be capable of imposing an increasing gripping engagement onto a pipe end within said fitting for resisting pullout forces externally encountered against said pipe end.
