Then, wipe the fitting dry before turning on your water supply. or larger holes for 1/2-in. The majority of ferrules in the marketplace however, are manufactured from metals. The joint gets most of its strength from the slight taper on the inside of each fitting, so a reasonably straight cut is necessary for a good fit. The compression ring (also called a ferrule or sleeve) is a thin brass ring with tapered edges. Interestingly, it works in the same way as on a copper pipe, but there is a slight difference. Compression fittings are most commonly used with hard tubing because the tubing wall must be rigid enough to resist the compression forces applied by the ferrule. So the first thing to do is to ensure that you pipe is free of any kinks, debris or just plain old dirt, so get yourself a clean paper towel or rag and clean it off as best as you could. What Type Of Compression Fitting Should I Use On Plastic Tubing? The functioning principle of each component also remains more or less the same between designs: tubing is inserted into the end of the fitting, and the nut/screw is tightened, forcing the ferrule(s) into the fitting body. To completely seal your copper or brass compression fittings, you could use a pipe jointing compound or PTFE tape. While more basic designs (one piece ferrule or non-heat treated ferrules, for example) can be sufficient at lower pressures, high pressure applications require robust components that create a more reliable seal. In most cases, its safe to use a compression fitting on any water line, providing you properly stabilize it. (The O-ring was pulled out for visibility.).
