HIGH PRESSURE COUPLING APPARATUS Abstract of the Disclosure Concrete pumping conduits are connected by releasable hinged couplers. The ends of the conduits include metal pipes formed with annular grooves including a circular peripheral base and a stepped and wall immediate adjacent the end of the pipe to define a pair of generally parallel and radially extended, in- clined sidewalls. The coupler is formed with inwardly projecting legs with the inner walls similarly stepped and defining a pair of generally inclined radial sidewalls offset in accordance with the offset of the grooved sidewalls, but slightly less than such spacing. A sealing gasket is located within the base of the cup- shaped recess with a tongue-like ridge projecting between the two end faces of the pipe ends. The first radially outermost side- walls of the coupler and the radially innermost sidewalls of the groove engage upon closing to provide a mechanical connection. The gasket is collapsed to seal the joints. The inner secondary, coupling sidewalls of the coupler and pipe grooves are spaced slightly from each other in the closed position. If the first sealing walls breakdown or roll over, the secondary sidewalls move into engagement resulting in a continued operable coupling. The gasket is recessed adjacent the ridge to define adjacent chambers with the outer sidewalls to define lips in sealing en- gagement with the conduit. The peripheral ends of the pipes are chambers and engaged by the sealing lips. -0-
