I purchased this mount fitting for my industrial power tools and I am impressed with its simplicity and durability. As a result of my tests, i determined that it provides the perfect amount of pressure to maintain a consistent flame while cutting metal. The brass construction makes it tough enough to resist corrosion even in high moisture environments. However, the price of this tool is a little bit high for most people`s budget .Overall, the Acetylene Regulator CGA200 Mount Fitting is an essential tool for every industrial and scientific worker..
