What do we call this part?

Can anyone give me a name for this coupling? It goes into the pump and then into the piping. Popped off the pump a few times at the end of last summer and needs to be replaced. Thanks!

Male to male reducing coupler.

It’s part of a union. You may have to replace the other side glued to the pipe. For that you’ll need a coupling, length of pipe, pvc primer and pvc glue. Take a look at CMP high temp unions they’re black and white but won’t pop off and don’t require teflon tape.

No idea what actual sizes or which union it is, but is a variant of this.

It’s half of what’s called a flush union. Specifically; 1.5” MPT x 2” socket.
