United StatesThank you to the young man that understands customer service, I now have the part that I ordered. Thanks to a good employee!
I used to to stop backflow between my compressors, pneumatic air dryer and my air tank. It basically prevents over pressurization from the heat of the day and prevents my air dryer from cracking as a result. Works great.
