Unfortunately these Buttress adapters do not fit any of my four plastic drums. The female thread is perfect for my 2 inch male thread PVC fittings, which is what I wanted to use for my 2 inch PVC pipe, so that part works perfectly, but the coarse male is too small for my drums. So, quality is good, looks perfect in the photo, but the description is misleading.
