The handle serves as a tool to remove the air valve if you choose to use water to inflate. **Q: What is the difference between this and the tp34? there is a slight price difference and the 34 is a waffled body. anything else that is significant?** A: hello, the TP34SB has a smooth body and is easier to use if you need the test plug to be a little more flexible in the pipe. the TP34 is just the waffle body which means its more stiff and obviously has more rubber. i hope this helps and if you need any more information please do not hesitate to reach out. thanks -GT Water Products Team ## Frequently Bought Together - Safe-T-Seal TP34SB Pneumatic Hydraulic Test Plug Inflatable with Air or Water, 3 to 4 Inch - VIAIR 6 ft.
