## Description

Maxitrol Gas Pressure Regulator.

Review: Great for natural gas generators - I got this regulator to connect my outside generator to my house natgural gas line. It worked great and does exactly what it is supposed to do. The setup was simple and the build feels solid. One thing I did change was the NPT vent protector. I replaced the original one with a version that is rain and weather-proof since the unit is sitting outside. Overall, it’s a reliable part and I’m happy with how it performs.
Review: American Made - High Quality and working perfectly with minimal adjustments…would highly recommend

## Questions & Answers

**Q: Does this product come with the vent limiter and what does the 66 stand for?**
A: Yes , this unit comes with the vent limiter.  The vent limiter is that small brass fitting you see on the image , screwed in vertically. Vent limiters are designed for use indoors and in spaces where limiting the amount of gas escapement due to diaphragm failure is critical.
