Great Innovation - beats the more costly and difficult to use bulkhead fittings
These little gems are so handy for making pvc and abs connections in things like sisterns, garbage cans, or whatever you need to connect a pipe to. They replace the more difficult to fit bulkhead fitting with this highly flexible and easy to install rubber grommet that is water tight and lasts. Plus a uniseal is less expensive than a bulkhead fitting. I keep several on hand for work on my Koi Pond.

Worth every penny going with this brand instead of a cheap one.
At first I didn't realize there was this brand and bought cheap ones. Every one of them leave even with silicone. I purchased these installed and not one drip. The quality is night and day.

Great concept but.
Make sure you have the exact size key hole saw to cut hole or will not work properly. Need to use thin wall pipe and the material that you are drilling through need to be pretty sturdy. Ended up going a different direction.
