Sander/shop Vac adapter

Hello! Does anyone know where we got our adapters that connect the shop vac to the orbital sanders in the woodshop?

I’m looking to connect the following two Dewalt Models. The one that came with my sander doesn’t connect well to my shop vac.

Sander: DWE6423

Shop Vac: DXV06PL-QT
