2" Plumbing to Inside 2" Pipe Adapter 2" slip x 2 1/8" Barb, Strong Spa

You are buying on a 2" Slip X 2" Barb Adapter.. This adapter glues inside of a 2" PVC plumbing fitting and a 2" Inside Diameter Tube glues onto the barb..  This part is found in Strong Spas and some others I will list them as I find out what they are but this is not the normal way to attach your plumbing hose to manifold and such..
