## Questions & Answers

**Q: What size is the bolt and how long is it?  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

### ⭐⭐⭐⭐⭐ Very easy and good quality sewer cap .
*by I***H on January 12, 2026*

Very good for a sewer clean out cap. Fit perfectly and tightened by hand no tools sealed perfectly.

### ⭐⭐⭐⭐⭐ Simple and works perfectly
*by C***N on March 5, 2026*

Does exactly what it’s supposed to do. The wing nut tightens easily and creates a good seal. Great for testing plumbing lines or temporarily plugging a pipe.

### ⭐⭐⭐⭐⭐ Best RV dump plug
*by R***Y on July 21, 2025*

A buddy of mine put in an RV dump that goes into his septic tank. I got this plug and installed it instead of the PVC screw on plug and it's awesome! Those screw on ones are fine when you first buy them, but when they get dirt in the threads, or the plug gets damaged or it's super cold out, etc, etc, they are a pain to remove and re-install. Well, for me they are because I have Parkinson's and my hands don't do what I want them to. This little unit works so easy, and you can use it on threaded or smooth pipe openings and it seals tight no matter what. Even with the tight fit, it is still easy to remove. It's built rock solid too
