These Air Tube Diffusers are manufactured in the USA. They are designed to be a drop in system. The rubber membrane is wrapped around a hollow PVC tube. The air holes in our tubes are a little larger than other brands so you get a medium size bubble which does not clog and puts very little back pressure on your system. This gives you a very low maintenance and effective aeration system.
