It does a good job regulating the low pressure gas to the house from the high pressure tank regulator. Used yellow gas pipe teflon paste and no leaks.Much less costly than what some gas companies charge for their regulators.

Purchased to put in-line with our Generac generator, which I installed as a back-up to our solar/battery system. I needed to get the WC down to 9-11" and after installing and running a test with a Manometer attached, the WC was a steady 9" which is adequate for the generator operation, and steady at 11" at non-op. It has been put to test several times in six months since installation and has worked flawlessly.

I needed a LP regulator for my whole house generator after measuring the supply line pressure at 2.7 psi. I needed less than 5”w.c. presented to generator motor.
