2" to 1"1/2 adapter for Polaris pool cleaner connection

This adapter is designed for connecting the Polaris (180/280/380/3900 Sport) to the suction point of your pool shell. It is almost impossible to buy this simple thing to a reseller ! And it often breaks...

Thread is on the one side 2" BSP (shell side), and on the other side 1"1/2 (Polaris adapter side). Thread were generated very simply thanks to Autodesk Fusion 360.

The adapter thickness is 15 mm, but you may want to reduce this down to 10 mm.
