Product Description
A fluoropolymer fitting with a tube holding section on the nut that utilizes a 2-stage system for securely holding tubes in place.
[Features]
· Quadruple-sealing construction (PAT.) provides a strong sealing effect and highly reliable performance against the leakage of liquids.
· Offers outstanding flow-through characteristics with minimized liquid pooling.
· The seal lock on the nut helps prevent loosening.
· The trapezoidal thread allows for the application of high levels of torque.
· Shows strong resistance to tube bending and deformation. The tube support allows it to withstand use with lateral loads.
· Simply screw-in as far as the ends of the fitting to tighten the nuts. No need for gauge management for positioning.
· For use at 200°C. The trapezoidal thread prevents the angled insertion of nuts.
· The reducer system allows you to switch tube sizes without having to change the body itself.

Notes For Tubing
Using the dedicated tube connecting tool (example)
1. Use the dedicated tool for connecting tubes.
| Body size | Torque (N·m) |
|---|---|
| 2 | 0.3 to 0.4 |
| 3 | 0.8 to 1.0 |
| 4 | 1.0 to 1.2 |
| 5 | 2.5 to 3.0 |
| 6 | 5.5 to 6.0 |
Note: For body size 1, tighten by hand.
2. Tighten the nut as far as the end surface of the main body. In order to confirm that it has properly reached the end surface of the main body, tighten by a further 1/8th (approx.) of a turn.
You will know that you have sufficiently tightened the nut if it will turn no further past this point. Be sure to also refer to the appropriate tightening torques shown to the left for when tubing/piping.
