I'm not a certified plumber, yet I've done lots of plumbing. This compresses the rubber seal for a leak free application even within a rough uneven rusted surface like what I've dealt with.

Too tight in a toilet drain. There are other products that work better.

The gripper was too large and would not fit into the cast iron sewer pipe. So I returned it and used the 3 inch gripper, which works fine.

      Very easy to tighten
      [This review was collected as part of a promotion.] The Oatey 4" mechanical End-of-Pipe plug is very well made and ergonoical. The wingnut is large with wide ears making it easy to tighten down. The fit is good and it seals/does it job well!

        Butter Fingers?
        For those afraid of dropping this in the drain, order some nylon string. An ounce of prevention beats a pound of cr@p ! Otherwise, expand it fully before fitting, then slowly retract until it will barely slip in, insert, then tighten. However, keep in mind that this is really only intended for pressure testing a system, not all the clever uses you guys are coming up with. It should not be used as a cool new projectile for your potato cannon. (Where did my wife put her hair spray and my PVC pipe? I've got to try that.)

          I have never had much luck with this product. Maybe I'm not cut out to be a plumber.

          Plugs 3 inch pipe
          I was not sure this would close the pipe I was working with. It fit nicely and tighted down to fill gaps

          These things sure are handy. I use them when working on my koi filters. They work great in areas that you can’t or don’t want to use ball valves for.

          These are great to get a tight seal as the nut and bolt expand the black rubber seal as needed for your application.
