3/4" Uniseal Flexible Tank Adapter - Perfect for Attaching 3/4-inch pipe to Curved Surfaces, Storage Drums, Buckets, and More - Ideal for Situations Where Bulkheads Fail - 12 Pack

Using these Uniseals to build out my aquaponics system's bell siphons, etc. No leaks so far!

These provide a perfect water-tight seal.

Used these for years, they are awesome but hard to remove once installed, use a little oil or soap to help install. I’ve never used caulk but I’ve seen some people do it. Never leaks

Product worked great for me. Drilled a 1 1/4" hole in a barrel. Used a 3/4" uniseal with 3/4" PVC with a pig watering nipple on the end. No leaks. It's amazing and the pigs don't break them off.But... my pack of five 3/4" uniseals had 4. The 5th one was 1/2". I got the job done, but I have one piece I won't be using.

worked but had to add jb weld marine to seal tight

The media could not be loaded. We use this to connect pipes or hoses to our water tanks. We use ibc tanks on our offgrid property and it’s a quick and easy way without having to use water proofing material

I bought some water barrels (used olive barrels) which were pre-installed with threaded, plastic fixtures. The installed fixtures were miserable, flimsy, and leaked. The Uniseal was a perfect fix when paired with some PVC pipe. Now I can install whatever valve or connection I want and don't have to worry about leaks. Unlike screw down bulkheads, this seal isn't impacted by temperature expansion/contraction and works on the rounded surface of a barrel.

Pretty well working but one did leak
