Uniseal® Pipe-to-Tank Seals

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 and pushed into the seal. 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.
