| Intru-Lok® | |
The Intru-Lok bite type fitting was developed by Parker Hannifin and introduced to the U.S. market in the late 1950’s. This fitting addresses those applications that require a bite by the ferrule in brass, copper, aluminum and plastic tubing systems. The Intru-Lok 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-Lok fittings allow the fitting assembler to visually inspect the bite quality, thus significantly minimizing the risk of improper assembly and related service problems. Intru-Lok fittings are routinely used in markets, such as: Machine tools, chemical, oil refineries, paper making, thermoplastics processing, air and lube lines, pilot lines, panel boards, etc. |
