Abstract: A fluid flow coupling assembly includes an inlet housing defining an inlet channel communicating with a first bushing recess and an outlet housing defining an outlet channel communicating with a second bushing recess. The assembly includes a bushing defining a flow bore communicating between the inlet channel and the outlet channel and a first bushing section disposed in the first bushing recess and a second bushing section disposed in the second bushing recess. The inlet and outlet housings are coupled to the bushing such that the inlet housing rotates about the bushing independently from the outlet housing. The first bushing section is retained between opposing walls of the first bushing recess and the second bushing section is retained between opposing walls of the second bushing recess.

Abstract: A suction coupling includes a first union coupled to a second union. The first union includes a first tubing joint extending from a side of the first union and a male flange extending from an end of the first union. The second union includes a second tubing joint extending from a side of the second union and defines a female receptacle formed in an open end of the second union. The male flange is rotatably coupled with the female receptacle such that when suction is applied to the second union, the first union forms a liquid seal relative to the second union.
