A Better Seal?
Hoover central vacuum, model S550. The exhaust port on the unit is aluminum, and the regular 2" PVC central vac pipe fits over it, but I was wondering if there is a coupler (perhaps rubber, something like the inlet coupling) to connect the pipe to this outlet? Just pushing the PVC pipe over this outlet does not create an effective seal, and there is dust on the wall where the unit is mounted.
