Its innovative Du Pont Alcryn material creates 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 replacing complex hardware with a single injection-molded unit, reducing labor and costs for professionals who demand reliability and efficiency. ## Description 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. ## Features - Made in the USA - 100% Guaranteed - Installs in minutes - Compatible with tanks up to 3/8” wall thickness - Comes with detailed instructions ## Technical Specifications | Specification | Value | |---------------|-------| | Size | Small | | Material | Rubber | | Brand | GREEN GOODS | | Colour | Black | | Connector Type | Adapter | | Thread Size | 2 inch | | Thread Type | NPT | | Number of Pieces | 2 | | Manufacturer | The Uniseal Warehouse | | UPC | 637262982579 | | Item model number | ikjnlk-958 | | Package Dimensions | 20.3 x 9.1 x 1.9 cm; 105 g | | ASIN | B072QR9KR6 | ## Product Details - **Size:** Small - **Material:** Rubber - **Brand:** GREEN GOODS - **Colour:** Black - **Connector Type:** Adapter - **Thread Size:** 2 inch - **Thread Type:** NPT - **Number of Pieces:** 2 - **Manufacturer:** The Uniseal Warehouse - **UPC:** 637262982579 ## Images ![2" UNISEAL Flexible Tank Adapter (Bulkhead) - 2 Pack - Image 1](https://m.media-amazon.com/images/I/61mbLiN7KSL.jpg) ![2" UNISEAL Flexible Tank Adapter (Bulkhead) - 2 Pack - Image 2](https://m.media-amazon.com/images/I/71Ppb1K2hkS.jpg) ![2" UNISEAL Flexible Tank Adapter (Bulkhead) - 2 Pack - Image 3](https://m.media-amazon.com/images/I/71f6PZzqA2S.jpg) ![2" UNISEAL Flexible Tank Adapter (Bulkhead) - 2 Pack - Image 4](https://m.media-amazon.com/images/I/712g7acyxeS.jpg) ![2" UNISEAL Flexible Tank Adapter (Bulkhead) - 2 Pack - Image 5](https://m.media-amazon.com/images/I/71-NQIgtopS.jpg) ## Questions & Answers **Q: What size hole is needed to be drilled for the 2 inch Uniseal?** A: The 2 inch uniseal requires a 3 inch hole **Q: This is supposed to create a watertight, but if I use this on a sump pump to prevent sewer gas from escaping, should I also use a sealant?** A: These work great.
