I am in need of replacing my 2" hose for a double blower set up. My original Sullivan has been okay but I have had to cut it down several times here recently because of blow outs. I saw a few people in Denver last year and at KILE this year with an all black hose that looks pretty heavy duty and the people like it better than the gray Sullivan ones. It has welded adapters on the ends (no hose clamps holding the ends to the hose). The people at KILE said they got it at an OH show but none of our local show suppliers know about it. Is anyone familiar with this hose and where to get it? It looks like a Plastiflex Hi-vac hose except all black but I'm not sure.
