## Questions & Answers

**Q: What are the ID of the 2 x 1 1/4 rubber coupling?**
A: 1 and 1/4 x 2 are the size if inner diameters

**Q: Is it possible to use for car exhaust**
A: I wouldn't.  Exhaust pipes get hot and this isn't heat resistant.

**Q: Will it melt?**
A: I want to know this answer as well. It doesn't say in the specs what temperature is allowed, neither transient nor continuous. From Wikipedia: The heat stability of raw PVC is very poor, so the addition of a heat stabilizer during the process is necessary in order to ensure the product's properties. Traditional product PVC has a maximum operating temperature around 60 °C (140 °F) when heat distortion begins to occur.[25] Melting temperatures range from 100 °C (212 °F) to 260 °C (500 °F) depending upon manufacture additives to the PVC. The linear expansion coefficient of rigid PVC is small and has good flame retardancy, the limiting oxygen index (LOI) being up to 45 or more. The LOI is the minimum concentration of oxygen, expressed as a percentage, that will support combustion of a polymer and noting that air has 20% content of oxygen.

**Q: 2” to 1 1/4” adapter Is bigger inside opening than stated.  Can a 1 1/4” p trap seal correctly?**
A: I used to connect 2” to 1 1/2”.  Both pipe were schedule 40. A P trap is normally a lighter schedule. You may need and adapter from 1 1/4” P trap to 1 1/4”  schedule 40.

### ⭐⭐⭐⭐⭐ Great quality Perfect solution for my Sump Pump.
*by M***D on May 12, 2026*

Used this for my Sump pump because I was installing a quite check valve. The check valve was a different size than the pipe for the sump pump. The Supply Giant 6I52 Flexible PVC Reducing Coupling was a perfect fit. No leaks. good quality and was easy to install.

### ⭐⭐⭐⭐ Good quality, but didn't work for me
*by M***W on January 15, 2019*

A nice coupling with an integrated stainless hose clamp. I thought the listed sizes were the inner diameter. Instead, I think these fit over pipes of that diameter (live and learn...). This is probably known to the plumbers using these, but I was looking to use them in a vacuum system. Included here are photos of the true inner and outer diameter of the 2" x 1 1/4" coupling so they can be seen. The coupling won't work for me, but it appears to be well made.
