Product catalog summary

Overview: The Intru-Lok® Flareless Bite Type Fittings, developed by Parker Hannifin, are designed for applications requiring a secure bite by the ferrule in various tubing systems such as brass, copper, aluminum, and plastic. These fittings are widely used in industries like machine tools, chemical processing, oil refineries, and more.

Design and Construction: The fittings consist of three main components: a body, a precision-machined ferrule, and a nut. The ferrule bites into the tube's outer surface to hold it against pressure and forms a pressure seal against the fitting body. This design allows for visual inspection of the bite quality, reducing the risk of improper assembly.

Advantages: The Intru-Lok fittings offer a leak-free and vibration-resistant connection, with ease of assembly due to the ferrule and nut not needing removal before tube insertion. A knurled nut option is available for areas with limited wrench clearance, allowing hand tightening.

Specifications: The document provides detailed specifications for various fitting types, including dimensions, pressure ratings, and part numbers. Dynamic pressure ratings are provided for each fitting type, ensuring suitability for specific applications.

Assembly and Installation: Instructions for assembly and installation are referenced, emphasizing the importance of following guidelines to ensure proper fitting performance.

Material Specifications: Standard material specifications are available in the appendix, ensuring compatibility and performance in different environments.

Key Components and Types: The document lists various fitting types such as union elbows, tees, crosses, plugs, and caps, each with specific dimensions and pressure ratings. These components are essential for creating reliable connections in tubing systems.
