Will this work or do you have a bigger one?** A: I bought some pills that claimed they could expand my 4" tool to 5.5". We're both out of luck, buddy. **Q: how is this product filled with air? can you use a bicycle tire air pump or must it be an aircompresor?** A: We used a portable air tank, that we filled at the local gas station. The fitting is for a car tube type valve, not sure if a bicycle pump has the same fitting, but if so it should inflate the product. We have such confidence in this that we have purchased another one just as a stand by. **Q: How big does this inflate to. I have an old size that is 5 terocada pipe. Would this be able to plug that pipe?** A: 4.25" is max for a 4" plug **Q: Would this product create an air tight seal?** A: I filled a 4" sewer line up with water and plugged it with the test ball plug and had no leakage. So it works well for water. There was no pressure in the line, so if you are talking about air pressure and how much, not sure if it was designed for that. ## Frequently Bought Together - Cherne 270040 Rubber Test Ball Pipe Plug, 4" , Black - VIAIR 6 ft.
