Where can I buy 2" fume hose?

[Jacob John]

And a 4" split to 4" and 2" pvc? I'm trying to tie my Tykma exhaust into my Trotec exhaust and need both the 2" hose and a splitter. Both are like unicorns it seems, or maybe I'm not using the proper terminology. Rockler has 2.5" hose but that appears to be the smallest I can find. Now the Tykma exhaust is flexible so it might be possible to squeeze a 2.5" hose down on it, but I'd prefer to find a 2" if I can. Any suggestions on either parts?

Not sure if that link will work, but you can go to McMaster.com, search "Duct hose", and see a ton of different options. Some of it is pretty expensive but if you only need a few feet it might get you where you need to be.

I've got a vacuum hose that is about 1.5" ID, ribbed with wire. Connecting to my blower gives me about 2 CFM per hour flow down the 25' hose. Make sure it is smooth interior or forget it and just neck down from 4" at the laser.
