3 400 atalog Intru-ok Flareless Bite Type Fittings Introduction The Intru-ok bite type fitting was developed by Parker Hannifin and introduced to the U.S. market in the late 950 s. This fitting addresses those applications that require a bite by the ferrule in brass, copper, aluminum and plastic tubing systems. The Intru-ok fitting is a flareless fitting that consists of a body, a one-piece precision-machined ferrule, and a nut. On assembly, the ferrule bites into the outer surface of the tube with sufficient strength to hold the tube against pressure. The ferrule also forms a pressure seal against the fitting body. Intru-ok fittings allow the fitting assembler to visually inspect the bite quality, thus significantly minimizing the risk of improper assembly and related service problems. Intru-ok fittings are routinely used in markets, such as: achine tools, chemical, oil refineries, paper making, thermoplastics processing, air and lube lines, pilot lines, panel boards, etc. Fig. E Intru-ok omponents: Body, Ferrule and ut Design and onstruction The three components of Intru-ok fittings are designed and manufactured to produce a reliable, leak free joint upon assembly. The Intru-ok Body Intru-ok fittings bodies are available in over fifteen configurations. The shaped products (i.e., elbows, tees, and crosses) are hot forged, then machined to the stringent Intru-ok fitting specifications. Straight products are made from cold drawn bar stock. The cold drawing operation ensures consistently tight dimensional tolerances, as well as significantly improved strength. The Intru-ok Ferrule Intru-ok fitting ferrules are precision machined with all dimensions and surfaces, particularly the critical bite edge, monitored on an ongoing basis. The Intru-ok uts Intru-ok fitting nuts are machined from cold drawn bar stock. The cold drawing operation provides a more tightly packed grain structure, thus improving the material s strength. In addition, cold forming significantly improves the fatigue properties or endurance limits of the nuts.

As the ferrule moves forward it contacts the tapered seat area of the body, which causes the ferrule to cam inward into the tube. The leading edge of the ferrule is thus able to make a clean 60 cut into the outside diameter of the tubing. This cut in the tubing is often referred to as a Bite ; thus the term: Bite Type Fitting. As the ferrule makes its bite, a small ridge of tube material is raised up in front of the ferrule. Rating The contact of the tube ridge with the ferrule s front face and bite edge gives the fitting its ability to retain pressure without leaking or blowing off. When properly assembled to the recommended tubing, Intru-ok fittings will consistently seal up to 500 psi working pressure in all sizes.
