Marshall Gas Controls 40410-12 12" Pigtail Acme Nut

I bought two of these hoses and their auto change over regulator. It was nice to be able to buy a product made in America and even better something made in Texas. I believe we should all start buying American made products.

First this was a bait and switch. What was delivered was an off brand and not a Marshall product. The picture Amazon shows you is not what I got. Cheap construction. Second, one of the two leaks and the other was reluctant to seat. I would have returned them but was leaving on a trip and hand to make do. I managed to repair the worst one my replacing a fitting with one in my workshop. Don't buy this junk. When it comes to something as critical as a gas connection, buy in person so you know what you are getting.

I ordered a pair of these to go with the new regulator I also ordered, but returned. These were then unneeded so returned them too. Great company to deal with.

Good product and very easy to install. I am expecting many years of safe usage from the things.

They don't leak witch is a good thing.

Does what it is supposed to. Open the valve and then gas goes through the hose and into the trailer......
