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: Good product / As described - Awesome product. Bought these to use when I made a bog filter. Worked well. Review: Worked great, no leaks - Nice seal. I didn't need anything extra for this to be perfectly leak free on my 55 gallon pond natural filtration bog filter. ## 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 | |---------------|-------| | ASIN | B0723HJ9KX | | Best Sellers Rank | #13,027 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #8 in Compression Bulkhead Fittings | | Brand | The Uniseal Warehouse | | Brand Name | The Uniseal Warehouse | | Color | Black | | Connector Type | Flange | | Customer Reviews | 4.7 out of 5 stars 990 Reviews | | Item Weight | 1 Pounds | | Manufacturer | The Uniseal Warehouse | | Manufacturer Part Number | ikjnlk-887 | | Material | Sarlink TPV 3460 | | Material Type | Sarlink TPV 3460 | | Model Number | ikjnlk-887 | | Number of Pieces | 2 | | Set Name | 2-pack | | Size | 1 Inch | | Thread Size | 1 inch | | Thread Type | NPT | | UPC | 637262982548 | | Unit Count | 2.0 Count | ## Product Details - **Brand:** The Uniseal Warehouse - **Color:** Black - **Connector Type:** Flange - **Item Weight:** 1 Pounds - **Manufacturer:** The Uniseal Warehouse - **Material:** Sarlink TPV 3460 - **Number of Pieces:** 2 - **Size:** 1 Inch - **Thread Size:** 1 inch - **Thread Type:** NPT ## Images ![1" UNISEAL Flexible Tank Adapter (Bulkhead) - 2 Pack - Image 1](https://m.media-amazon.com/images/I/618S3ud8s4L.jpg) ![1" UNISEAL Flexible Tank Adapter (Bulkhead) - 2 Pack - Image 2](https://m.media-amazon.com/images/I/71+2vJVp36S.jpg) ![1" UNISEAL Flexible Tank Adapter (Bulkhead) - 2 Pack - Image 3](https://m.media-amazon.com/images/I/71fveLEUFIS.jpg) ![1" UNISEAL Flexible Tank Adapter (Bulkhead) - 2 Pack - Image 4](https://m.media-amazon.com/images/I/71EsM5Fn0OS.jpg) ![1" UNISEAL Flexible Tank Adapter (Bulkhead) - 2 Pack - Image 5](https://m.media-amazon.com/images/I/71-NQIgtopS.jpg) ## Questions & Answers **Q: Can I use them on a round surface like the side of a 5 gallon bucket?** A: Yes, I believe they were made for that very thing! I used mine on the cover of a 5 gallon bucket. It's a tight fit, but works very well. **Q: Will a 1 inch OD work?** A: No, your pipe OD must be 1.315'' (33mm) just like 1 inch pvc pipe. **Q: How many pcs for 1 order?** A: You will receive two Uniseals. (2 pack) **Q: Are these seals NSF certified?** A: There is nothing that would indicate a NSF rating on the packaging or product. My answer is NO. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product / As described *by C***E on May 15, 2025* Awesome product. Bought these to use when I made a bog filter.
