Purchased to replace the Mac valve on RV airbags. It was broken and didn't work. This valve was the same valve that was originally on the RV. I sent the valve back. Checked the Mac website and found a Mac dealer. Bought two valves from the dealer. Both valves worked. My husband said that the Revain valve packaging was a different color than the Mac dealer's packaging. The retailer's valve packaging matched the color and lettering on the Mac website. Revain's packaging was different, and the imperfection leads me to believe that Revain was a fake, not a Mac. Attached is a picture of a valve purchased from a Mac dealer.
