Your cart is empty.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.

Make sure you lubricate them when you install them and you will have a better experience

Used two on a bog filter for a pond. Worked great. Used the recommended size hole saw, a little plumbing grease (silicone i think) and had no problems with the install.

I have used a lot of these in some diy stuff than needed a flexible bulkhead over the years. Fairly easy to install once you get used to using these. This 1 and 1/4 inch size needs a 2 inch hole for anyone wondering. I make them a hair bigger than 2 inch though because I have hade these split before if the hole was too tight. Maybe about 1/32nd bigger than 2 inch. As well as leak if it is a little too wide. Just make sure your material is compatible with these because in brittle material like glass or acrylics it can cause the said materials to crack or break. I have always used these on flexible plastics like polyethylene stock tanks, and hdpe rain barrels or buckets.
