Review: 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.
Review: hmmm - works great. great price compared to locally. only regulator I could locate that had the full bore fittings in the odd sizes and positions I wanted for my LP system. Output pressure set perfectly at manufacturer.
