Engineered from durable PVC and Du Pont Alcryn, it creates a liquid-tight seal that withstands up to 65 PSI and resists harsh chemicals and temperature extremes. Compatible with tanks up to 3/8” wall thickness, this 6-pack offers professional-grade reliability and efficiency for plumbing, rain barrels, fish ponds, and more. ## 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. Review: Works great with lo leaks! - I used these on 4 rain barrels. You will have success when using a 1.75" saw bit and 1 inch pvc piping. Review: Excellent uniseals and worked great 1" - Needed these for my small fish pond barrel . Worked great. Hint…with a file or grind stone, just put a small chamfer on the end that goes into the hole. Worked great. ## Features - Made in the USA - 100% Guaranteed - Installs in minutes - Comes with detailed instructions - Compatible with tanks up to 3/8” wall thickness ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B093WZD6B7 | | Best Sellers Rank | 333,078 in Garden ( See Top 100 in Garden ) 8,153 in Garden Hose Parts & Connectors | | Brand | GREEN GOODS | | Colour | Black | | Connector Type | Adapter | | Connector type | Adapter | | Customer Reviews | 4.6 out of 5 stars 80 Reviews | | Item Dimensions | 7.6 x 7.6 x 1.3 centimetres | | Item Weight | 0.16 Kilograms | | Item dimensions L x W x H | 7.6 x 7.6 x 1.3 centimetres | | Manufacturer | The Uniseal Warehouse | | Material | Polyvinyl Chloride | | Number of Pieces | 6 | | Set Name | 6 Pack | | Size | 1 inch | | Thread Size | 1 inch | | Thread Type | NPT | | UPC | 736542138931 | | Unit Count | 1.0 count | ## Product Details - **Size:** 1 inch - **Material:** Polyvinyl Chloride - **Brand:** GREEN GOODS - **Colour:** Black - **Item dimensions L x W x H:** 7.6 x 7.6 x 1.3 centimetres - **Connector type:** Adapter - **Thread type:** NPT - **Item weight:** 0.16 Kilograms - **Number of pieces:** 6 - **Manufacturer:** The Uniseal Warehouse ## Images ![1'' UNISEAL Flexible Tank Adapter (bulkhead) - 6 Pack - Image 1](https://m.media-amazon.com/images/I/71H1WNgLB6S.jpg) ![1'' UNISEAL Flexible Tank Adapter (bulkhead) - 6 Pack - Image 2](https://m.media-amazon.com/images/I/71fveLEUFIS.jpg) ![1'' UNISEAL Flexible Tank Adapter (bulkhead) - 6 Pack - Image 3](https://m.media-amazon.com/images/I/71EsM5Fn0OS.jpg) ![1'' UNISEAL Flexible Tank Adapter (bulkhead) - 6 Pack - Image 4](https://m.media-amazon.com/images/I/71+2vJVp36S.jpg) ![1'' UNISEAL Flexible Tank Adapter (bulkhead) - 6 Pack - Image 5](https://m.media-amazon.com/images/I/71-NQIgtopS.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great with lo leaks! *by T***E on 29 July 2025* I used these on 4 rain barrels. You will have success when using a 1.75" saw bit and 1 inch pvc piping. ### ⭐⭐⭐⭐⭐ Excellent uniseals and worked great 1" *by 5***S on 18 April 2026* Needed these for my small fish pond barrel . Worked great. Hint…with a file or grind stone, just put a small chamfer on the end that goes into the hole. Worked great. ### ⭐⭐⭐⭐⭐ Great for low-pressure uses *by A***Y on 18 October 2025* I am using these in conjunction with a 55 gallon plastic drum for a filter for my duck pond as well as water for my chickens' water bar. For low-pressure applications like this, it's working perfectly. Much easier to install and cheaper than a bulk-head fitting. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/504058918-1-uniseal-flexible-tank-adapter-bulkhead-6-pack](https://www.desertcart.tn/products/504058918-1-uniseal-flexible-tank-adapter-bulkhead-6-pack) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-14*
