Review on Powertec 70175 Dust Collection Hose: Efficient Fittings, Two Reducers & Black Color by Byron Patil

Do any of these work? God invented duct tape for users in the dust collection industry. Shouldn't the "adapter" fit inside or outside of the part it's trying to fit? It seems that everyone is just leaning against each other or far from what is needed. I used a hookah for my runs and trying to hook up 6 different machines to it was like going to DMV, VA and having Flu x 10's rolled up in a bunch. The dust collection industry is against all of us who don't use the full 4 inches. The hose is well made and durable. It's flexible enough. Consider buying a heat gun if you want to glue parts and tape together.
