1. An assembly having multiple components that couple first and second pipes together having different pipe sizes, comprising:
a housing that allows a flow of fluid through the assembly, the housing having a housing inlet with housing inlet threads that are threaded externally and configured such that the assembly threads to a first pipe having a first size, having a housing outlet with a housing outlet mating surface and housing outlet threads, and having an inner passageway that has an inner circumferential rim that allows the flow of fluid from the housing inlet to the housing outlet;
a body adapter having a body adapter inlet with a body adapter inlet mating surface that couples to the housing outlet mating surface having a body adapter inlet circumferential groove or channel with an O-ring in a sealing manner forming a mating surface coupling when the body adapter is coupled to the housing, with a body adapter opening that allows the flow of the fluid from the housing outlet to the body adapter, and with a body adapter inlet coupling flange, having a body adapter outlet with outlet threads that are threaded internally and configured such that the assembly threads to a second pipe having a second size that is different than the first size, and having a body adapter inner passageway that allows the flow of the fluid from the body adapter opening, through the body adapter and to the second pipe; and
a locking ring having an inwardly and circumferentially extending flange that couples to the body adapter inlet coupling flange and forms a flange coupling configured such that the body adapter inlet mating surface and the housing outlet mating surface mate and seal when the locking ring is coupled to the housing, and having a locking ring portion with locking ring threads that thread to the housing outlet threads and couple the locking ring to the housing;
the mating surface coupling together with the flange coupling forming an assembly union (U) that orients and aligns the multiple components of the assembly, forms a sealing relationship when the assembly is threaded to the first and second pipes and allows a transition from one pipe size to another pipe size.
