Query: no wonder it was on sale

I purchased two cyclone seperators, one for each dust collector,so far,I cannot find a 30 gal or any other garbage can for which to get a snug fit. I worked so hard to get my dust collection system air tight that I can't see using a device where the 4"hoses fit so loosely that you can see light around the connections and the lid is totally loose around the all the cans I tried. There are no instructions or tips to seal this device and if you try to return it you incur a restocking fee.
