### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect
  

*by A***X on Reviewed in the United States on June 3, 2023*

Worked as expected. Just drilled a normal hole as directed, didn't sand or anything, and it works great.

    Best seal I have used!
  

*by M***R on Reviewed in the United States on June 17, 2021*

We built a filter for our little pond.  It works well.  It was difficult to figure out how to push the pvc pipe in but we figured it out.  My husband and I have lost strength over the years.  But he got the bright idea to use a bar clamp to push the pvc pipe through the uniseal.  It worked great!

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Easy and Don't Leak
  

*by D***A on Reviewed in the United States on June 12, 2015*

These things are great and work on curved surfaces--never had one leak yet. For the larger ones, get a rough file and bevel the edge of the pipe A LOT and back about 3/4 inch. Smear silicone inside the uniseal. Use a tee on the end of the pipe to have something to push with. I use these on containers for pond filters and on fish tanks. Also created filters from flower pots and aerial bucket liners using these. Also worked on a preformed pond, old swimming pool sand filter (on the curved part) and one of those filter falls. I have had bulk head fittings leak but never a uniseal.
