Large LP Regulator.
Works great. I installed it on my 40' motorhone external 100# LP tank, and now I don't have a reduction in flow when it gets cold.

First Stage LP ordered for spare
This regulator is used as a first stage regulator for LP gas at the storage tank and is set for 10 PSI exit pressure. The unit is easy to mount.

Good product, not the right application
The only reason I'm not giving this item a 5 star rating is because in my application I should have chosen a higher pressure regulator. This regulator operated exactly a advertised and deserves 5 stars in the right application. I'm running propane from a 200 gal tank to my RV. The things I read said I should reduce the tank pressure to 10PSIG to prevent sludge from building up in the hose. However, 10PSIG barely gives me enough pressure at the RV to run it. A 20PSIG regulator would be best.
