After removing the toilet, I discovered the existing toilet flange was offset rather than centered. My initial concern was that the plug might not fit properly or create a reliable seal. Fortunately, those concerns disappeared as soon as I installed it. The plug fit perfectly into the flange, and with just a few turns of the wing nut, the rubber expanded securely against the pipe walls and created a tight, solid seal. Installation took only a couple of seconds and required no special tools. The construction appears robust, with a sturdy plastic body, galvanized hardware, and a thick rubber sealing surface. Once tightened, it remained firmly in place without any movement. Most importantly, it completely sealed the drain and eliminated any concern about sewer gases entering the room. For anyone repurposing a bathroom, remodeling, or temporarily removing a toilet, this is a simple and effective solution. Overall, this is one of those products that does exactly what it's designed to do. It's well made, easy to install, provides an excellent seal, and gives peace of mind that the drain is properly capped. Highly recommended. Review: Plugs my ground level sewer clean out perfectly - I had a clean out pipe in the backyard broken off just above the ground. The area is shaded and the soil has rocks in it. I would have had to dig a hole about a foot deep and 18” across. Not to mention the cost of the pvc pipe and fittings. I saved at least $45-50. It took me about 30 seconds to install and tighten by hand. A perfect seal and fit. It seems durable and is easy to see since it is bright red. Very easy and secure installation. ## Features - Made in China ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000H5T1PI | | Best Sellers Rank | #3,866 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Expansion Plugs | | Brand | Oatey | | Brand Name | Oatey | | Color | Red | | Customer Reviews | 4.7 out of 5 stars 1,929 Reviews | | Global Trade Identification Number | 00038753334035 | | Included Components | (1) Mechanical plug | | Item Dimensions W x H | 1.75"W x 3.75"H | | Item Type Name | 4-in.

Thanks.** A: I measured the bolt at 3/8" threaded diameter with 2 1/4" of threaded length. Since this is not specified in the description and other bolt lengths would work the same, it may be you'd end up with a different bolt length. **Q: Would this stand up to the abuse of an ATV, as a dry storage tube cap?** A: I would think so. It’s pretty sturdy **Q: Will this seal the 31/4" cleanout hole in 4" cast iron sewer line?** A: This plug properly fits a 4" hole. Mine is in use so I cannot measure it. However, I also purchased the 3" plug and I believe it would be more appropriate. At max, it achieves about 3 1/8 seal. If you wrap enough material around the 3" you might get a more usable product. **Q: End of RV slinky storage tube is 4.5 " diameter. When rubber is compressed will this be tight enough to survive vibration of normal travel?** A: It's meant to hold fast in a firm pipe, like PVC. I wouldn't recommend it for a hose or pipe with give. The rubber gasket only moves out a little bit when tightened. Maybe you could get a large hose clamp and tighten it down outside your hose after you cover the end with aluminum foil. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect Solution for Capping an Unused Toilet Drain - Sealed Tight and Installed in Seconds *by M***E on June 6, 2026* I purchased this Oatey 4-inch test plug to cap the drain after removing a toilet from an unused half bath that we're converting into a linen closet.
