Replacement Propane Regulator for Fairview GR 630
Updated 01/15/2026 | Published 01/14/2026 >
Question:
I have a Fairview LP gas regulator model GR 630. Your specs on it says it has a 1/4 inlet and outlet. When I measure the inlet and outlet on mine it is a 1/2 across the opening. So are these the same regulator?

Hey Clifford, I checked out the specs of your Fairview LP gas regulator model GR 630 and it uses the same 1/4 inch FTP inlet and outlet like what the part # 37207-30325 you referenced is designed for. This also is rated for the same high pressure as the Fairview so it would be a great replacement. What are you using this with?

So I need to buy one of the Fairview 630 regulators and I will need two hoses One to go from the tank to the 630 regulator and one to go from the 630 regulator to the main Fairview regulator/ distribution valve. They don't need to be but about 6-8 inches each. Do you guys have such hoses or will I need to go have them made?

I have a 2018 cardinal fifth wheel trailer. It has 2 propane tanks, one on each side. The right tank will supply propane to the gas appliances the left tank has never supplied propane. The tanks are connected to a Fairview gas regulator that has a valve that lets you chose which tank you want to use. I noticed that the right tank has this small red Fairview regulator in line before the main regulator the left tank doesn't have one. So I swapped the hoses on the main regulator and the right tank still delivered propane and the left still did not. So I have concluded it is not the main regulator and I need to put a small Fairview regulator on the right tank.
