2" Uniseal Flexible Tank Adapter - Perfect for Attaching 2-inch pipe to Curved Surfaces, Storage Drums, Buckets, and More - Ideal for Situations Where Bulkheads Fail - 2 Pack

Nice seal. I didn't need anything extra for this to be perfectly leak free on my 55 gallon pond natural filtration bog filter.

Works well even on curved surfaces like 55 gallon barrels.

Cheaper and easier to use than screw in bulkhead connectors!

Good product and the solution to sliding 2 inch pvc into it is....boil some water. Once water is boiling, turn off heat. Put seal into the water for about 2 minutes. This made it pliable enough to slide the pipe in. Also I beveled the end of the pipe and used no lubrication other than saliva.

I like this seal option for making my own inlet and outlet for 30 gal grey water sump, for before sending sink drain to a leach field line. I experimented with a 2 and 7/8" - 73mm hole on my tank first for a 2" ABS pipe insert to 3 " hole. I was worried the 3" might be too loose after one reviewer said his was (might have been with PVC insert? ). I found I needed to re-drill with 3" - 76mm hole saw (taped previous cut out center back in place to drill to 3"). That worked great for my 2" ABS pipe insert. I used soapy water for lube, and pressed my short 2" ABS pipe in with a little wiggling while also applying lots of pressure. I am sure tapering the end of that 2" ABS with a razor knife was helpful. Like this best way to seal an inlet and outlet for a tank that I have used to date.

I am using this for a slightly different putpose than what it was made. I have plumbing pvc for a future bathroom sticking out of concrete floor in my basement gym area. I laid LVP flooring and had to cut around the pipe. I am using the seal ring to trim around the pipe and hide the floor cuts. I will paint the pipe black and put a boot over the top until I ever decide to add a bathroom. It works great and fits in with the industial style I was going for in the basement.

Good

Great way to connect rain barrels together in a series
