## Questions & Answers

**Q: Is this cap UV rated for outdoor exposure?**
A: I am not sure but I use mine outdoor. I have it for about a year and so far it seems fine.

**Q: What is the heat rating?**
A: 140 Degrees F.

**Q: Any idea if this would stretch enough to fit over the outside of a 3" coupling?  i would like to plug a 3" coupling that has the pipe cut off flush.**
A: I bought 2 of the 4 inch size. They fit 4 inch pvc pretty tight. They would definitely not fit over the a 4 inch coupling. The 3 inch size most likely will NOT fit over a 3 inch coupling.

**Q: The OD of my pvc sewer pipe is 3.5".  What size cap should i get?**
A: Probably the 4 inch pipe and tighten the clamps the 3 inch might be to tight

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product!
*by S***R on June 30, 2025*

Great product! Fit my 4.5 inch PVC opening with little adjustment.

### ⭐⭐⭐⭐⭐ Great cap!
*by L***. on April 16, 2025*

This is not an exciting product but is definitely perfect for my needs. It slips easily over my sewer cleanout and stays on tight. Very happy with this cap so far! Great price too!

### ⭐⭐⭐⭐⭐ Works great!
*by L***G on October 7, 2024*

I needed a cover for an electrical outlet conduit that was outside. The opening was 6" and no one has them. I grabbed this, installed it and tested it with my garden hose. Leak free and it's made very well. In less than 2 minutes my piece of mind was back. Again, super well made!
