Good primary regulator for the money.
Have used this as a primary regulator on the outside of a food trailer. Works perfectly. Would buy again if it ever became necessary. Just remember, you will still need a green secondary regulator closer to the gas appliance.

These are right hand threads on the input side.
Not sure why but the threads on the end where the pigtail screws into the regulator are right hand threads. I was unable to use this one since the my application needed to be left hand threads. I ordered a different one and they were as needed. Seemed to be a well built product though and the one that worked for me is the same brand.

Worked ok for two years, then failed.
Worked as intended for about two years, then noticed a strong gas smell near the tank. Found that the regulator was venting a lot and had to replace. Should have lasted longer for the price.
