Flareless Tube Fittings consist of a body, a one-piece ferrule, and a nut are available in carbon steel, brass, and stainless steel. With a large number of configurations, there will be a fitting that is ideally suited to meet the requirements of almost any industrial application. On assembly, the ferrule “bites” into the outer surface of the tube with sufficient strength to hold the tube against pressure and seal the fluid, without considerable distortion of the inside tube diameter. Hydraulic fittings have a visible bite, allowing the fitting assembler to visually inspect the bite quality, thus significantly minimizing the risk of improper assembly and related service problems. Flareless Tube Fittings are especially suitable for use with tube wall thickness ranging from medium to extra heavy. For proper bite, bottoming out the tube is essential for the make-up of the fitting. Leak-free performance is guaranteed when bite type fittings are assembled properly. No special tools are required to obtain proper installation.
