Heat or cold can change the resistance of the spring inside the regulator. How to find the correct pipe thread sizeWARNING: The NPT thread size is NOT referring to the size of the thread itself!The plumbing industry standard for the pipe sizes is NOT always as straightforward as measuring the pipe.Measuring the pipe will often mislead you into choosing the wrong pipe size.The "pipe thread size" is measured and based on the inside of the pipe. A lot of people measured the thread / the opening for the thread / outside diameter of the pipe, and thought that was the thread size. It was WRONG.The NPT thread is referring to the Interior Diameter of the pipe.

## Questions & Answers

**Q: I need a regulator for my tankless water heater. has to be three-quarter inch in and out and deliver 7 to 9 wc  . will this regulator work for me?**
A: No. Please search the ASIN B00851MEVE for a propane gas regulator. It is 5.5 to 12 wc, slightly adjustable. Thanks.

**Q: I need a 25 PSI with a 6 inch water column natural gas regulator for my generator.  Will this one work?**
A: Yes it will work but it will come closed so no gas will make it through in order to get it to work you need to remove cap In the center of the unit and turn the screw that you see then remove blue cap and discard

**Q: I have a commercial kettle corn popper. It's 160 qt pot and I need a regulator that is highnout put with a gauge that I can see is running at 20 psi.**
A: This is NOT the regulator you want. 
You need a red painted regulator, it's adjustable and made for your application, I also think 20 PSI is overkill, 10 PSI is a lot of pressure.

**Q: Does this come with the one hose on the output side?**
A: The regulator is sold as is. Hoses are sold separately.
