Its weight is 0.79 Pounds. You have been told about this item because of the 4-inch rubber stopper. Now examine some bullet points of it;
PVC plastics are used in the construction of it. It has a design similar to a Cap that can be easily fit on the pipe. It has great sprinkler applications. It is stronger if we use PVC Primer and Glue to attach with the pipe. It was the product that introduces a 4-inch Rubber Stopper.
