Gas shut off valves

[Sneakinup]

Gas shut off or turn on valves I mean.

I have a few stuck old crusty gas valves underneath my trailer that I want to replace. Does anyone have any recommendations for what to use? Are they generally available at home centers?

I want to replace the one just before my water heater as well as the one to my propane heater.

Thanks in advance!

Take one with you.

The brass parts section at Lowe's or HD should have them, but when you get there there will be many different sizes, hence the above advice. There is nothing too special, the LP is under such low pressure at the valve that the basic brass one will work just fine.
