We used these 1 1/2" UNISEAL flexible tank adapters in multiple places across our aquaponics system—including connections for our sump tank, radial flow filter, and bioreactor—and they’ve performed flawlessly. They provide a super tight seal without the need for bulkhead fittings or threading, which saved us time and headaches during setup. Installation was easy with the right hole saw and a bit of soapy water. Once the pipe is pushed through, the seal is rock solid. We’ve had zero leaks, even with regular water flow and occasional jostling of pipes during system maintenance. This 2-pack was a great value, and the flexibility of the UNISEALs made adapting to curved barrels and IBC totes a breeze. If you're building or upgrading any kind of aquaponics or hydroponics system, these are an excellent choice.

This is one of those inventions that make life easier. Follow the instructions, and in like 5 minutes, you have a reliable, robust seal. One set now is about a year in, and no signs of a leak. And all of the seals worked the first time. Which is critical on a rain barrel, because once that hole is cut you can't un-cut it! Sealing a rain barrel pipe is a particularly difficult problem, because the pipe is at the opposite end from the barrel opening, which is too small to easily manipuilate interior parts like nylon washers, or nuts. The uniseal eliminates that whole problem by having no internal components. If only EVERY product did what it claimed as these little gems do! I found this invention on another site, but I've purchased all of mine here, and I could not be more pleased. As a qualifier- I only use them in low-pressure applications (rain barrels). I don't know how they do under higher pressures. But in my case they are the BEEZ KNEEZ!
