This fitting is mainly used for connecting a 2" male threaded item (like a pond or water feature pump) to our flexible PVC pond and water feature pipe 50mm or other sizes with adaptors.

One side is a 2” threaded female and the other side is a double purpose slip solvent weld. Internally its a 50mm slip female adaptor and on the outside its a 63mm male adaptor (you will need a 63mm female slip fitting or socket to connect to our 63mm male piping).

You're looking at a 2 inch female threaded adaptor which accommodates 50mil solvent pipe work.
