Great for low-pressure uses
I am using these in conjunction with a 55 gallon plastic drum for a filter for my duck pond as well as water for my chickens' water bar. For low-pressure applications like this, it's working perfectly. Much easier to install and cheaper than a bulk-head fitting.

It works as expected
Easy peasy, I drilled a 1.75" hole, inserted the Uniseal into the hole, and then put my pipe through. I like that I can still adjust the height if needed (it's part of a bell siphon), but it's stiff enough that it won't leak or move on its own.

I've stopped using bulkheads since I found these items
I keep ordering these uniseals as they are remarkable, I'm always surprised at how water tight the joint or the fitting that I place inside of these things are I've never had a leak and I've been using them for almost a year now the PVC that I put inside of it is really tight and snug. It's a bit hard to get the PVC in there but that's how I was supposed to be. There's no leaks and it feels perfect. This is my third time purchasing a set price is good always quick shipping and the qualities is Ammazing really had from rubber. I use these things when creating a DIY filtration system for my pond.

Works well if it works at all
These seals work better than a different brand I've tried, but there may possibly be some quality control issues. One of them I received was defective.

Works great
These have solved a lot of my bulkhead issues for a lot cheaper. Will definitely be ordering again.

No leaks, easy to install.
I saw these on a video and tried them out. It's been a couple of weeks and I'm really impressed, I used them on a food grade plastic drum and there have been no leaks and an easy install.

I used these on 4 rain barrels. You will have success when using a 1.75" saw bit and 1 inch pvc piping.

I bought these to make my own garbage can pond filter. I can honestly say that I was skeptical that they would, but I am amazed to say that they worked perfectly! They come with info on how large you need to drill the hole for the PVC pipe and everything. I highly recommend!
