## Overview

The 1 1/2" UNISEAL Flexible Tank Adapter is a premium, USA-made bulkhead seal designed for quick, tool-free installation. Crafted from durable Alcryn, it forms a superior liquid-tight seal up to 65 PSI, compatible with tanks up to 3/8" wall thickness. Resistant to chemicals, heat, and cold, this 2-pack adapter streamlines plumbing connections by eliminating traditional hardware, saving time and reducing costs for professionals.

## Description

Uniseal is simply the world's best seal and installing the Uniseal is a simple process. After cutting a hole in the wall of a tank or other surface, the seal is inserted. Then the pipe is coated with a slippery detergent (i.e. dish soap) and pushed into the seal. Uniseal products replace traditional plumbing hardware with a single injection molded unit requiring no component parts. It was designed to solve many of the issues of pipe to tank connections. For many industries pipe to tank seals are traditionally among the most complex connections to manufacture. Traditional seals require multiple parts such as, rigid flanges, bolts, washers, o-rings, along with long assembly times and high production costs. The Du Pont Alcryn is the key to the liquid-tight seal. When the pipe is pushed through the rubber-like Uniseal from the outside, the inside Alcryn wall becomes thin enough to allow the pipe to squeeze through and then forms a liquid-tight seal. The coefficient of friction with the plastic pipe is roughly three times higher than any other material which allows it to create a better seal than with any other material. In static conditions the seal is good up to 65 PSI. Uniseal can withstand pressure, and suction, acids, oils, greases, gasoline, sewage, waste, heat and cold. It offers long life, easy installation and reduced labor and material costs.

Review: Reliable, Leak-Free Seals for Aquaponics—Highly Recommended! - 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.

### ⭐⭐⭐⭐⭐ EZ Install, Perfect, Reliable Performance!
*by S***E on June 19, 2018*

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!
