ADJUSTABLE CEMENT HEAD MANIFOLD An adjustable cement head manifold connector including a first union having a passageway therethrough operably connected for a fluidtight connection with a cement head, a second union having a passageway therethrough having an end for operably connecting it in a fluidtight manner to a cement head, means for slidably connecting the first union and the second union in a fluidtight manner. The means for slidably connecting including a mandrel having one end fixed to one of the unions and slidably engaged with the other. The fixed end of the mandrel is preferably held with a combination of a sleeve surrounding the mandrel acting in conjunction with a nut which operatively engages and presses the mandrel against the seat at the opening of the union. The end of the mandrel which is slidably engaged utilizes a piston nut and O-ring arrangement for fluidtight engagement against the mandrel. Alternately, a turnbuckle sleeve may be utilized with left and right hand threads connecting to the unions to provide additional reinforcement One end of the union has a foreshortened end which is made possible by the use of a segmented retainer sleeve held in place by a snap ring and motivated by a flanged nut which engages the retainer ring. |
