Outstanding
I used these to install 3 inch PVC piping for a homemade undercurrent deep water cultivation system. They were exactly as described and what current culture provides, work wonderfully with prescribed hole saw dimension and even offered better then expected customer service when I found another online retailer with a slightly lower shipping cost. Very happy

Great product and price
Beats a bulkhead anyday - so cheap and effective :) On these 90mm ones I grind slits about 1cm down around the end and also round the edges. Then I use vegetable oil and it goes in like a glove. Use a 102mm hole saw.

I have used Uni-seals from 1" up to 4" for 6 years and will only use them. In that time I have used at least 100 plus and I have not had a single leak. Best product out there for Aquaponic systems, tanks and grow beds. Highly recommend them.

Me
Used these making a multi-barrrel Koi filter system. I have never used them before, but was disappointed in them. I used 6 of them, but had leaks around 2 of them after 2-days. I had to drain and dry the system and siliconed around them inside and out of the barrels. I will know tomorrow if my silicone job worked.

Rain barrel application
I purchased the 3" Unusual for my rain barrel project and it works great. No leaking or problems. I like this company. They are very fair with the shipping since it's pretty much an unbreakable product. Thanks

Didn''t work for me
The concept is good, I''''m sure, but I found it VERY difficult to push the ABS pipe through (even with plenty of recommended dish soap), and there is still a leak between the Uniseal and the tank.
