Patent abstract
The present invention provides an expansion-deflection coupling which allows for higher angular deflection, as well as greater axial expansion and compression with increased parallel offset movements. The coupling includes a pair of identical hubs adapted to accommodate conduits within, and a flexible hollow cylinder extending between the hubs. At least one mid-coupling is located within the cylinder, and at least two plastic funneled tubes, each of which extends securely within the cylinder between the mid-coupling and one of the hubs. One of the hubs is secured to a union coupling.
