[!] FECT has I.D. penetrated. Tube can be set at any desired portion by passing it through the body.
[!] Size 8-1 is applicable only for FENL.
[ ! ]E dimensions are only for FENL, and the inner diameter of FECT is the same as the outer diameter of the applicable tube.

[ ! ] 1. Fluororesin (PFA) tube is used in the measurement.
(1) Remove the nut from the fitting and insert it into the tube.
(2) Insert the tube into the fitting.
(3) Tighten the nut to secure the fitting and tube.
2. General tolerance of tube is absorbed if the nut is tightened by the above torque value.
3. Number of revolution is begun to count up when tightening becomes fixed suddenly after lightly tightened by hand.
[ ! ] When using hard tubes such as fluororesin (PFA) tubes, tube inserts are not required.

· Features
Excellent in chemical resistance.
Possible to tighten the nut with a spanner without using special tools.
