Bend the tube into a U shape
at a temperature of 68°F
(20nC). Fix one end and bend
the loop gradually at 100
mm/min. Measure 2R when
the tube breaks or is crushed.

How to Order
Note 1) There may be plasticizer (white powder) deposits on the external surface of the tube. Please be careful when the
tube is used in clean rooms. Otherwise, the clean level may decrease.
Note 2) When solvent is used, make sure to test in the same environment as the actual operating environment, and
confirm that no problem will occur in the operating conditions. The standard value of the Applicable Fluid List
below is the reference value based on the test result performed under specific conditions.
The product can be physically affected by temperature, pressure, chemical density, etc, causing permeation or
swelling, and this may cause some problems.
Note 3) Perform periodic maintenance inspections. If leakage continues to occur after tightening, replace the tube with a
new one. (Refer to Maintenance in the Specific Product Precautions on page 2.)
When the tube rotates, perform a test to make sure no problem occur in the actual operating conditions.
When the product is used with motion for a long time, or at a high temperature, the tubes may have leakage due
to deterioration of the materials.
Note 4) Observe the lesser value of the maximum operating pressure between the tubing and fitting. The surge pressure
must not exceed the maximum operating pressure. If the surge pressure exceeds the maximum operating
pressure, it will result in damage to tubes and fittings. Furthermore, abnormal temperature rise caused by
adiabatic compression may result in the tube bursting.
Note 5) Minimum bend radius (refraction value) is not guaranteed. The value of 2R in the left figure is measured with a
bent or flattened tube.
Note 6) For the installation of fluoropolymer fitting LQ1 and LQ3, please contact SMC.

effects
may occur such as penetration and swelling due to temperature, pressure and chemical
density. To use tubing in a solvent environment, tests should be performed with the same
environment to ensure no problem occurs with operating environment.
Note 1) “Chemically inert” means – not to cause any chemical reaction.
