The Swagelok A-401-PC is a 1/4 inch aluminum port connector made from 6061-T6 aluminum alloy, a high-strength, heat-treatable material widely used in aerospace and defense. This specific alloy is chosen for its excellent strength-to-weight ratio and high resistance to corrosion.
Product Specifications According to Swagelok product catalogs and technical data: Part Number: A-401-PC. Material: Aluminum alloy 6061-T6. Size: 1/4 inch Tube O.D. at both ends. Weight: 1.28g Design: A straight port connector with one machined ferrule end (acts as a tube adapter) and one tube fitting end. Cleaning: Typically processed under Swagelok's Standard Cleaning and Packaging (SC-10).
Installation Instructions The assembly procedure for a port connector differs from standard tube fittings. According to the Swagelok Installation Guide: Preparation: Remove the nut and ferrules from the Swagelok end connection where you intend to install the port connector. Discard those ferrules. Assembly: Slip the nut over the machined ferrule end of the A-401-PC. Tightening: Insert the port connector into the end connection and rotate the nut until finger-tight. While holding the fitting body steady, tighten the nut exactly 1/4 turn for this 1/4-inch size. Note: Do not follow the standard 1-1/4 turn rule used for tubing, as this can over-stress the machined ferrule end.
Technical Performance Pressure Rating: Swagelok aluminum fittings are generally rated to the working pressure of the tubing they connect to. For 1/4" 6061-T6 aluminum systems, this is typically around 2,100 to 2,400 psi. Temperature Range: 6061-T6 maintains its structural integrity from -58°F to 300°F (-50°C to 148°C).
