Tubing Connector Nuts, low pressure, 1/16 inches, Delrin, mixed colors with 1/4-28 screw threads, for use with flange free, polymeric tubing. ARE-Applied Research brand. 10/PK.
Additional Info:
The 45216‑X‑K Delrin Tubing Connector Nuts (10/Pack) are low-pressure fluidic fittings designed for connecting 1/16 inch OD flangeless polymeric tubing in HPLC systems and other fluid handling applications. These finger-tightened connector nuts provide a fast, reliable connection method without requiring tubing flanging.
This configuration includes mixed colors within each package, allowing easy visual identification of flow paths, systems, or users while maintaining consistent performance.
Manufactured from Delrin™ (polyoxymethylene), these fittings offer high stiffness, low friction, and excellent dimensional stability, making them ideal for routine use in low-pressure flow paths.
