Connect 37mm hose to Jet Sander

[cortes]

I have a Jet belt/disc sander with a suction port with an outside diameter of 1.5". Since the Festool hose is 37mm or 1.46", a 1.5" inside diameter connector should work to connect them. An Internet search didn't turn anything up and I was wondering if anyone else has handled this problem.

If you have a heat gun, and about 5 minutes, you can use a 1" PVC coupler. 

The coupler will be about 3mm too small.  I dug through my chrome sockets until I found one that was the right OD.  Heat the PVC coupler up until it gets soft, then force it onto the socket.  Once it's cool, you can pop it off and it stays the same size.

My Kreg Foreman is about the same size as the Festool/Bosch hoses I use, so I did both ends of the coupler and it's perfect.

If you have access to a 3D printer it would be easy to make a model of this that you could print.

I would try a flexible pipe fitting. I used one to connect a 27mm hose to my Bosch SCMS

Works very well. I tighten the end on the SCMS and leave the other end loose. My hose end slides right in snugly.
