Union Flange LQ1F Metric Size Fluoropolymer Fittings / Hyper Fittings (LQ1F41-1)
A metric size type fluoropolymer fitting with outstanding sealing performance and leakage-prevention reliability.
[Features]
· Quadruple-seal construction.
· Offers outstanding flow-through characteristics with minimized liquid pooling.
· For use at 200°C.
· The seal lock on the nut helps prevent loosening. The trapezoidal thread allows for the application of high levels of torque.
· The tube holding section on the nut utilizes a 2-stage system for securely holding tubes in place.
· 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.
· The trapezoidal thread prevents the angled insertion of nuts.

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. Refer to the appropriate tightening torques detailed below.
