  • Maximum Operating Pressure: 101.5 Psi G
  • Applicable Fluid: Liquid
  • Applicable Tube Material: PFA or PTFE
  • Material of Nut: PFA
  • Material of Body: PFA or PTFE

PFA Fluoropolymer Tubing and PFA Fitting


The development of such revolutionary fitting is made possible by our business model, introducing the following features:

►High resistivity against pulling makes a reliable fitting

PFA Fitting FIT-ONE Compression-Ring design is a perfect solution to the shortcoming of general flare type fitting.

The Compression-Ring firmly grips the tube, achieving high resistivity against pull.

The screw nut will pressure the Compression-Ring when fastened to the designated location, securing the conjunction between the PFA tube and the PFA body fitting.

►Small fluid pressure loss and easy replacement of liquids

Low torque fastening nut helps securing the flow of fluid path, minimizing the loss of fluid pressure while decreasing liquid remnants.

As a result, the replacement of liquids can be carried out easily.

Click-Gauge as the fastening reminder

The Click-Gauge indicates the optimal fastening location, maximizing the performance of the fitting without damaging it.

When the nut is fastened to the optimal location of the body, the gauge will notify the operator either through vibration or sound.
