Diba Click-N-Seal® Fittings with Flat-Bottom 1/4"-28 UNF(M) Thread for Flared Tubing

Achieve a leak-free seal with only the tube material in the fluid path
  • When the cap clicks, you know the seal is tight
  • Self-torquing fittings create a secure seal without the use of any tools
Fittings for flared tubing create a ferrule-free connection and ensure leak-free seal while minimizing carryover. As the fitting is tightened, the resistance of the cap increases until the correct torque is reached. A seal is created by compressing the flared portion of the tube against the flat bottom of the port.

Select from acetal, polycarbonate (PC), or PEEK™ material of construction. PEEK fittings are compact in design and provide excellent chemical resistance. Choose the size that best matches your tube OD. A washer is recommended to ensure the flare seals correctly. Use flanging kit to easily flange semi-rigid tubing.
