2-Layer Soft Fluoropolymer Tubing TQ Series (Part Numbers)

SMC

Tubing with a 2-layer structure.
[Features]
· Fluids such as solvents are transferred by flexible piping with superior abrasion resistance.
· Wearing of outer layer tube: Reduced to 1/30.
· Flexibility: Improved by up to 55% (*1). * 1: Compared with SMC Fluoropolymer Tubing / TL (ø6 [6‑mm diameter] × ø4 [4‑mm diameter]).
[Applications]
· Semiconductors, food, medical, machine tools.

(i)Caution

The maximum operating pressure values listed are at 20°C. See the catalog for details.
For specifications and details, please refer to the catalog.

Features Of 2-Layer Soft Fluoropolymer Tubing TQ Series

2-Layer Soft Fluoropolymer Tubing TQ Series: related images

How to measure the minimum bending radius

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

Applicable Fluid List

Fluids in the list below are chemically inert to tubing material. Possible physical 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 under the same environment to ensure no problem occurs under the operating environment.

1. "Chemically inert" means to not cause any chemical reaction.
2. Criteria: ◯ Applicable, △ Not recommended, × Inapplicable
3. Applicable Fluid List shows the reference values based on test results performed under specific conditions. Application to products is not guaranteed.
4. Applicable Fluid List is for tube materials. For use in environments containing solvents, please contact SMC.

1. There may be plasticizer (white powder) deposits on the external surface of the tube. Please exercise caution when using this item in a clean room. Otherwise, the clean level may decrease.
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 under the operating conditions. The standard values of the Applicable Fluid List below are the reference values based on the results of tests 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.
3. Perform periodic maintenance inspections. If leakage continues to occur after tightening, replace the tube with a new one. If the tube will be used in a location where it moves, perform a test to make sure no problems occur under the actual operating conditions. When the product is used with motion for a long time, or at a high temperature, the tubes may leak due to deterioration of the materials.
4. Observe the lesser value of the maximum operating pressure between the tubing and fittings. 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.
5. The minimum bend radius (tube close bend radius) is not guaranteed. The value of 2R is measured with a bent or flattened tube.
6. For the installation of fluoropolymer fitting LQ1 and LQ3, please contact SMC.
7. A fitting that seals the outer diameter of the tube such as a one-touch fitting is not applicable since it is in contact with the wetted part of the external layer nylon material.
