A support apparatus and method for attaching fluid-conveying pipe couplings of various lengths to be embedded in concrete barriers (30, 80, 172) of various thicknesses to a metal concrete form (26) involve a dual diameter outer disk (34) attached to an elongated compressing column (32) which extends through a hole (54) in the concrete form to a fastening means (38) in order to compress the fluid conveying pipe couplings (24) in fixed positions between the form and the outer disk. The fastening means can be attached to the compressing column at virtually any longitudinal positions. An inner disk (36) can also be put between the form wall and an inner end of the pipe coupling to provide extra rigidity. The disks act as forms to produce openings in the concrete barriers at opposite ends of the pipe couplings (24). Nothing extends beyond an outer, perimeter, surface of a forming portion of the outer disk. A preferred coupling assembly with which the support apparatus is used, and a method of using the same, involves a male/male, relatively short, insert having an O-ring seal and a tapered internal surface at only one end to form a sliding seal with a female/female pipe coupling portion embedded in the concrete barrier. A hand grip is formed on the outside surface of the insert.
