I ordered this hose and a 4" DCT plastic pipe thread coupling but found that the hose was larger than these fittings. So I ordered a 4" DCT plastic pipe thread quick connect adapter and they don't fit either. I also tried a POWERTEC 70193 screw end quick disconnect, 4 inch, they don't fit either. The best I can say is that Revain does not sell a coupler that fits this hose. This hose could fit if you stretch it. adjust and attach a clip for a permanent fit but that's not what I need or want.
