Ferrule for Compression Fitting 5qty

In piping and tubing-based systems, a ferrule is a small component used to seal a compression fitting assembly. Such compression fittings are necessary elements in a large variety of tubing-based applications, including plumbing, gas lines, and chromatography.The front ferrule creates a seal against the fitting body and on the tubing outside diameter. As the nut is turned, the back ferrule advances the front ferrule and radially applies and effective tube grip. Corrosion and chemical resistant.
