ABSTRACT:
A flexible pipe line joint having an annular housing with a central cavity in which a nipple is partially submerged. The nipple has a flared end on the submerged portion to the inner surface of which an elastomeric ring is adhered. The ring is internally contoured spherically with reference to a common center point spaced from the flared end and located on the longitudinal axis of the joint. An elastomeric body has an assembly of embedded concentric spherical rings and is adhered to the outer surface of the flared end. The spherical rings are contoured and positioned in symmetry to the common center point. A collar secured to the housing encircles the nipple and engages the outer surface of the elastomeric body to maintain the body in position. Support structure secured to the housing has an outward facing spherical surface mating in sliding relation with the internal surface of the first elastomeric body.
