DuPont Alcryn Uniseals® - connect pipes to tanks without bulky bulheads, tank connectors, nuts and bolts, "O" rings or messy silicone to fill the gaps and using only one part.

Uniseal® products replace traditional plumbing hardware with a single injection moulded unit requiring no component parts. They were designed by Dupont to solve many of the issues of pipe to tank connections for industrial applications. 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 for businesses.

The DuPont developed 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 higher using a Uniseal® than any other material which allows it to create a better liquid tight seal.

Uniseals® will connect pipes to complex contoured surfaces without deforming the tank and are compatible with both water and oil based materials.

Standard Uniseals® are made to fit ABS, PVC and steel pipes from 3/16" (5mm) to 6" (150mm) through tank/vessel wall thickness of 1/8" (3mm) to 1/2" (13mm).

The greatest assets to Uniseal® products are that they have a quicker and easier installation process and pipes can be removed and replaced at a later time.

There is no requirement to cut a pipe exactly to length to fit into a bulkhead, the pipe passes straight through the wall of the tank, whether it is a flat or curved surface, surrounded by the Uniseal® and no solvent welding is required. There is some leeway on the angle that the pipe passes through the Uniseal® (up to 15 degrees) so unlike normal bulkheads some building tolerance can be applied.

The effort is worth it, pipes and Uniseals® can be removed and with care re-used time and again. No more having to cut solvent welded fittings from pipes or having to fit expensive rubber boots due to design changes or mistakes. Want to change the design of your entry point into your vessel, simply leave the Uniseal® in place, leave a short length of pipe and cap it off. Uniseals® are also ideal for a hydroponic bucket system as with some care they are re-usable.
