Internal cap / cover for tubes or soil pipes

I designed these as dirt covers for soil pipes to protect the pipes from dirt getting in during building works. Works best on soil pipes with rubber seal but will also work with pipes which needs to be glued. With easy finger holes to put and remove the caps.
I included the diameters we use most (50-75-80-90-100-110 and 125mm). The photo enclosed is from the 125mm version.
