## Overview

The 1 1/2" UNISEAL Flexible Tank Adapter is a premium, USA-made bulkhead fitting designed for quick, tool-free installation. Crafted from durable Du Pont Alcryn, it forms a superior liquid-tight seal compatible with Sch 40 and Sch 80 PVC pipes, handling pressures up to 65 PSI. Ideal for tanks with walls up to 3/8" thick, this innovative adapter replaces complex traditional fittings with a single flexible unit, reducing labor and material costs while ensuring long-lasting, leak-proof performance.

## Description

Made in the USA 100% Guaranteed Works with Sch 40 or Sch 80 PVC Pipe Installs in minutes Compatible with tanks up to 3/8” wall thickness Made with Du Pont Alcryn Comes with detailed instructions Uniseal is simply the world's best seal. It is also incredibly easy to install. 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: Great Innovation - beats the more costly and difficult to use bulkhead fittings - These little gems are so handy for making pvc and abs connections in things like sisterns, garbage cans, or whatever you need to connect a pipe to. They replace the more difficult to fit bulkhead fitting with this highly flexible and easy to install rubber grommet that is water tight and lasts. Plus a uniseal is less expensive than a bulkhead fitting. I keep several on hand for work on my Koi Pond.
Review: Worth every penny going with this brand instead of a cheap one. - At first I didn't realize there was this brand and bought cheap ones. Every one of them leave even with silicone. I purchased these installed and not one drip. The quality is night and day.
