Abstract
A flexible tubing coupling employs ferrules at the tubing ends, each ferrule being connected to an annular end fitting by way of a bellows. The end fittings are statically secured together by retainer halves encircling the end fittings and captured there by a rigid ring. Engagement between ferrule rims and inner spherical surfaces on the retainer halves prevent undue extension and deflection of the bellows while maintaining a uniform stress distribution on the coupling components. Various end fitting static seal configurations are also disclosed.
