Tubing Connector Nuts, low pressure, 1/16 inch, Delrin, Red with 1/4-28 screw threads, for use with flange free, polymeric tubing. ARE-Applied Research brand. 10/PK.
Additional Info:
The 45216‑R 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.
Manufactured from red Delrin™ (polyoxymethylene), these fittings offer high stiffness, low friction, and excellent dimensional stability, making them ideal for routine use in low-pressure flow paths while enabling clear color-coded system organization.
