Fit in the pipe snugly, even before tightening the screw, which was awesome, because the pipe is vertical and I didn't have to worry about it slipping in. Once in place, I just tightened the screw. It blocked all the water. Not even a trickle. Love when i order something and it works as expected. Review: Worked like a charm! - Replaced an old rubber plug that wasn't sealing tight with this one and it worked great! ## Features - Tool, Winter Plug, Technical Products, #15, 3.86"od, 4" Pipe - #15 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01784VYE6 | | Best Sellers Rank | #218,501 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1,022 in Biscuits & Plugs | | Brand | Technical | | Brand Name | Technical | | Color | Black | | Customer Reviews | 4.4 out of 5 stars 62 Reviews | | Item Dimensions W x H | 4"W x 4"H | | Item Weight | 3.2 ounces | | Manufacturer | Technical Products | | Manufacturer Part Number | AQWP-15 | | Material | Nylon, Rubber, Stainless Steel | | Material Type | Nylon, Rubber, Stainless Steel | | Model Number | AQWP-15 | | Number of Items | 1 | | Product Dimensions | 4"W x 4"H | | UPC | 616312765546 | | Unit Count | 1.0 Count | ## Images ![TECHNICAL PRODUCTS No. 15 Rubber Plug for 4 Inch Pipe - Image 1](https://m.media-amazon.com/images/I/6134-L1NpTL.jpg) ![TECHNICAL PRODUCTS No. 15 Rubber Plug for 4 Inch Pipe - Image 2](https://m.media-amazon.com/images/I/714Zx5fkTIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked great! *by B***S on October 8, 2023* Needed this to stop water from entering my pond filter while I cleaned it.
