Tubing Connector Nuts, low pressure, 1/8 inch, 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 45208‑X‑K Delrin Tubing Connector Nuts (10/Pack) are low-pressure fluidic fittings designed for connecting 1/8 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 multiple colors within each package, allowing for easy visual identification of flow paths, systems, or users, particularly useful in multi-line or shared instrument environments.
Manufactured from Delrin™ (polyoxymethylene), these fittings deliver high stiffness, low friction, and excellent dimensional stability, making them ideal for low-pressure, higher flow applications.
